What is DBMS?

DBMS stands for “Database Management System.” It’s a software system designed to manage, store, organize, and retrieve data from a database. A database is a structured collection of data organized and stored to allow for efficient querying, manipulation, and analysis.

A DBMS provides an interface and tools for users and applications to interact with the database without worrying about the underlying complexities of data storage and retrieval. It offers various features and functions that facilitate data management.

Common examples of DBMSs include MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, SQLite, and MongoDB. Each DBMS has its strengths, features, and use cases. The choice of a specific DBMS depends on factors such as the nature of the data, scalability requirements, performance considerations, and application needs. DBMS Project Ideas

What is a DBMS Project?

A DBMS project involves creating a database management system designed to store, manage, and facilitate access to data efficiently. These projects typically focus on designing schemas, integrating data input forms, and creating queries and reports to manage large amounts of data effectively. DBMS projects are fundamental in industries like healthcare, finance, and education to handle complex data operations securely and reliably.

What is an example of a database project?

A DBMS project involves creating a database management system to store, manage, and retrieve data efficiently. These projects typically include tasks like designing schemas and building queries to handle data operations. An example is developing an inventory management system to track stock levels and transactions in a retail business.

The following are some easy and exciting dbms project ideas. Choose one according to your requirements:

1. E-commerce Platform

You must’ve seen multiple online retail platforms. Some great examples of such platforms are Amazon and Flipkart. In this DBMS project, you’ll have to develop a similar e-commerce platform, where a customer can register and buy a product.

You can also consider doing our Java Bootcamp course from upGrad to upskill your career.

Your developed platform should have a registration window where the user will provide their name, bank name, and bank account number. This information will enable them to make transactions easily. After they’ve registered, the system should give them unique user IDs and customer IDs. They should have the option to set up their passwords.

Any e-commerce platform would be incomplete without having any products to sell, wouldn’t it? So it should have product listings as well, classified according to their prices (or some other criterion). The user should have the option to buy one or more products from your platform. And after the user makes a purchase, the system would generate an invoice, which will contain the user’s name. The system can allow ordering from different suppliers according to availability.

Featured Program for you: Fullstack Development Bootcamp Course

Using DBMS for an e-commerce platform will give you extensive experience in this technology. It’ll help you understand how online platforms use and interact with databases. Still, this project will undoubtedly take some time and effort.

This project makes for one of the most relatable database projects , as e-commerce uses databases for tracking the transactions, and products database, the marketing team also uses the DBMS to track the traffic, acquire potential customers and retain the existing customers. The e-commerce industry is running on having a strong database because it is online and data is the new oil. Also, just having data is not enough, having the strong ecosystem of having a string core database is what makes it all efficient.

2. Inventory Management

Every organization has an inventory to manage, which takes up a lot of resources. Usually, an organization would assign the duty of inventory management to two or more people who’ll keep an eye on it and ensure that all the supplies are available. If any item is missing, the manager would order the same. This system works effectively if the organization is tiny, but that’s not always the case.

You can solve this problem of businesses and build an inventory management system. The goals of your design would be the following:

Increase the inventory turnover
Optimize the inventory and the stock levels
Reduce the number of safe stock levels
Get low material prices.
Make it easy to understand and access.
Reduce the operational costs of the inventory (storage cost, insurance cost, etc.)
Classify the objects in the inventory according to their stock levels

As you can see, an inventory management system will allow its client to save a lot of time and resources. They can find the stock levels in their inventory and plan accordingly. It will make the enterprise more efficient and productive.

This is one of the beginner-level database projects on this list. You can work on it even if you don’t have much experience with developing database solutions.

This is one of the good database project ideas , as inventory is the core of any business. Especially after the pandemic hit, most businesses have turned online. Not only the recently turned online businesses but the recent and old businesses were well. If an organisation has a solid core management system for inventory tracking, they could not only increase the business but also can understand the leakages.

Database Design and Normalization: Emphasizes the need for proper database structure to ensure data consistency and efficiency.
Basic Front-End Development: Highlights the inclusion of front-end development for data visualization to make the system more user-friendly.

3. Railway System

The railway network of our country is one of the most complex public establishments. You can design a database solution for this network and make the management of the same more natural. Your system should have the following pieces of information:

Station names
Tracks that connect those stations (to keep things simple, you can assume that only one track runs between two stations)
Train IDs with names
Schedules of the trains

The train schedules should have information on the stations from where the train starts and by when it reaches the destination. It should also include information on which stations it passes through during its journey.

To keep things simple, you can assume that every train completes its journey within a day, and they run daily. However, you’ll also need to store information on the sequence of the stations a train passes through. For example, if a train starts from Delhi and goes to Kolkata through Lucknow, then you’ll need to add the arrival and departure times of the train for all these stations. Keeping the stations in sequence will allow easy management of trains and their data.

Also visit upGrad’s Degree Counselling page for all undergraduate and postgraduate programs.

Till here, the project is rather easy. You can make it more challenging by adding the passenger information of every train such as its coaches, seat numbers, types of coaches, passenger names, and so on. This project might take some time to complete, but it’ll help you showcase your knowledge of database management solutions while solving a significant issue of a public authority.

India has a very big network of railways, not only that but the metros also have become a very significant part of commutation over the country. Both these types of railways have a wide network and people’s daily commutes depend upon them. Keeping a track of the train’s arrival, departure, first time of arrival at a particular station and last train departure also have a big role to play as people plan their schedules accordingly. Keeping a track of these is really important. Not only that but also keeping the tracks safe from collisions and any haphazard also is important for the smooth operation of the network. This brings another factor which is revenue, the need for revenue generation arises because of the large number of users. Keeping a track of tickets, and distance travelled is necessary in order to track the overall revenue which eventually helps in the country’s GDP. This is why is one of the important topics for the database project topics .

4. college data management.

Colleges have multiple departments where every department offers many courses. These departments have a head (HOD) and various instructors. Even though there are many instructors, one instructor can only work in one department. As you can see the organization structure of a college is quite complicated and requires a lot of effort to manage.

In this database project, you can build a solution to tackle this problem. It would store all this information about the college and its departments. However, the information we’ve discussed above isn’t sufficient for a college. We need to mention the courses as well.

A course can have only one instructor, but an instructor can have multiple classes. You’d need to add this information to the database system as well. You can make this project more advanced by adding the course enrollment information.

You can add the enrollment information of the students as to how many students have taken a particular course.

The system should allow easy access. Your developed DBMS-based solution would allow a college to save a lot of time and resources; moreover, the user could see all the college information from one place and modify it accordingly.

Along with that, colleges or universities hold a lot of sensitive information about their students’ such as-

Personal information
Bank Details
Parent’s information, etc.

These kinds of personal information need to be secured from online theft and unauthorised access. The security of this information is the responsibility of the college and universities. And this is why the university management system is one of the important topics for database projects.

5. library data management.

If you’re an avid reader, then chances are, you must’ve gone to a library. And you may already know how many books a library has to keep track of. Libraries don’t have a lot of staff, but they have to keep a record of all the books they have and the books they have lent. You can simplify the management of a library’s data.

You should start with students and faculties, i.e., people can get books from the library. Now, there would be a significant difference between the number of books a student can get and the number of books a faculty can get. So, add those limits in your system as well. Then, every book would have a unique ID.

Books with the same title and author would have different IDs according to their copies. You’ll have to add entries for every book. And then, add the details of who issued the book and when with the duration of their ownership. Your DBMS-based solution should also have details on the books that people haven’t returned and the due fines.

Along with keeping the labeling organised for the books, it is equally necessary to modify the data and keep constant track of the books which keeps getting published and returned. Also keeping the track of the worn-out books, restock, newly added books, etc. Along with that, libraries also maintain the data genrewise. All of these constitute the library database management system that helps the libraries run their operations on autopilot and also helps the librarians.

6. Solution for Saving Student Records

You can build a solution that saves student records for an educational institution. Handling student records is no easy feat. You need to keep their name, subjects, fees, any provision of concession, and their academic progress. A DBMS-based solution will allow the client to save a lot of time and effort.

Your design goal should be to have separate files for each student where the data will store information about the student. You can start by adding the following sections:

Student’s Name
Subjects (or Stream)
Grades (or Marks)
Concessions (or Scholarship)
Additional Information

It’s one of the easy database project ideas. You can take it a step further, and add the option to include students of different grades or sections. Your designed system should allow the admin to enter the details mentioned above. And the admin should be able to access it easily.

7. Hospital Data Management

Hospitals have unique data requirements. Not only do they have to maintain the medical records of their patients, but they also have to manage their staff and its multiple departments. You can solve the data-related problems of hospitals by creating a DBMS solution.

First, you should assign unique IDs to the patients and store the relevant information under the same. You’ll have to add the patient’s name, personal details, contact number, disease name, and the treatment the patient is going through. You’ll also have to mention under which hospital department the patient is (such as cardiac, gastro, etc.).

After that, you should add information about the hospital’s doctors. A doctor can treat multiple patients, and he/she would have a unique ID as well. Doctors would also be classified into different departments.

Patients would get admitted into rooms, so you’ll need to add that information to your database too. Apart from that, there would be distinct rooms (ICUs and Operation Theaters) in the hospital. Then, you’d have to add the information of ward boys and nurses working in the hospital and assigned to different rooms.

You can start with a small hospital and expand it as you move on. Make sure that the data is easily understandable and accessible.

Also, the hospitals have a lot of information with them such as the patient’s history, pharmacy, test results, number of beds, information about the helping staff, etc. All of this data needs to be managed as they are crucial to the hospital’s operations and helps in its smooth functioning. This database management helps in routine or emergency visits as well.

Which types of data do the healthcare industry hold?
What are the advantages of DBMS in the healthcare industry?
What are the disadvantages of not using DBMS in the healthcare industry?

Web-Based Software: Emphasizes the development of a web-based system for accessible and centralized management.
Modular System Design: Organizes hospital operations into distinct modules for better manageability.
Administrator Control: Ensures that only administrators can manage and access the system, enhancing security.
Comprehensive Patient Management: Includes management of admission, discharge summaries, and ongoing treatment updates.
Integrated Pharmacy Management: Incorporates pharmacy inventory and billing into the system.
Appointment Scheduling Features: Adds the functionality for scheduling and managing appointments.

8. Blood Donation Management

Another DBMS project idea is to create a blood donation clinic. You should start by adding donor names and assigning them unique IDs. Add their details and relevant information such as blood type, medical report, and contact number. Similarly, add patient names with unique IDs, details on their medical conditions, and blood types.

After you’ve created a database of patients and donors, you can work on a database for the blood bank. There, you’ll have to add the name of the blood bank, its staff details, operating hours, and address.

DBMS is helpful in the blood donation industry by keeping the track of the acceptors and donations. This helps the hospital in keeping a record of the blood donors as well in case of any emergency. And also to help them keep track of the storage.

9. Payroll Management Solution

Managing payroll is one of the most crucial aspects of an organization. So you can create a database solution for this purpose as well. Here, you’ll first have to assign a unique ID to every employee. And then, you’ll need to add the details of the same employee, such as their name, role, department, etc. You’ll have to add information on the unpaid salary of the employee, and the date on which the salary has to be released. Similarly, you’ll have to add the time from which the salary is due.

After that, the database would need the information on the HRA, DA, medical allowance, and other additions to the basic pay. Similarly, you’ll need to add data on the deductions you need to make (if there are any) such as extra leaves. You can add more difficulty to the project by creating a management solution for a significant organization. In this one, make sure that you add the departmental details of the employee under his/her ID.

What are the Types of DBMS?

Several types of Database Management Systems (DBMS) are designed to cater to specific data management needs and scenarios. Here are some of the main types of DBMS:

Relational DBMS (RDBMS)

This is one of the most common types of DBMS. It organizes data into tables with rows (records) and columns (fields) and establishes relationships between tables using keys. SQL is typically used to query and manipulate data. Examples include MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, and SQLite.

Object-Oriented DBMS (OODBMS)

These systems are designed to handle complex data structures, including objects with attributes and methods. They are useful for applications that deal with object-oriented programming languages. Examples include ObjectStore and ObjectDB.

Document DBMS

Also known as document stores or NoSQL databases also store and retrieve data in flexible, schema-less document formats like JSON or XML. They are well-suited for storing and managing semi-structured or unstructured data. Examples include MongoDB, Couchbase, and CouchDB.

Key-Value Stores

These databases store data as key-value pairs, where each value is associated with a unique key. They are efficient for simple read-and-write operations, making them suitable for caching and high-throughput scenarios. Examples include Redis, Amazon DynamoDB, and Riak.

Columnar DBMS

These systems store data in columns rather than rows, which can provide significant performance benefits for certain analytical workloads. They are optimized for data warehousing and business intelligence applications. Examples include Apache Cassandra and Google Big Table.

Graph databases store data in nodes and edges, representing entities and relationships between them. They are designed for managing and querying highly interconnected data, such as social networks or recommendation systems. Examples include Neo4j and Amazon Neptune.

Time Series DBMS

These databases are designed to handle time-stamped data, such as sensor data, logs, and financial market data. They provide efficient storage and querying mechanisms for time-series data patterns. Examples include InfluxDB and OpenTSDB.

NewSQL Databases

These are a new generation of relational databases whose main aim is to combine the advantages of traditional databases via scalability and performance capabilities. For examples CockroachDB and NuoDB.

Spatial DBMS

These systems, such as geographic information systems (GIS), are specialized for storing and querying spatial data. They enable efficient manipulation and analysis of location-based information. Examples include PostGIS and Oracle Spatial.

In-Memory DBMS

These dbms projects store data completely in memory by offering high-speed data retrieval and processing. They are often used for real-time analytics and applications that require rapid data access. Examples include SAP HANA and VoltDB.

Frequently Asked Questions (FAQs)

Database Management System (DBMS) software applications essentially structure and organize data files to provide easy access and standard data assortment. It essentially categorizes the data system so that the user can derive the required information from heaps of data. While Structured Query Language (SQL) isn’t a database management tool, it’s a programming tool that helps access the database. It is linked to the Relational Database Management System (RDBMS), wherein specific user queries are processed to retrieve desired data from the system.

Database Management Systems (DBMS) have made data storage and retrieval much more accessible. Any DBMS needs to have an excellent design for the data to be stored systematically. The DBMS must be designed so that users can access and navigate through the system quickly. A good design ensures uniformity in the data structure to create a reliable DBMS. It should strategize data to avoid duplication of results and increased storage usage. Data design focuses on creating a simple design structure to prevent complexity in locating data and reduce DBMS maintenance.

A file system is essentially categorized as a Database Management System (DBMS) owing to its purpose. However, compared to DBMS, a file system stores data comparatively primordially. Files are taken and stored categorically; however, like DBMS, their relevancy or connection is not mapped out. Hence, retrieval of files gives a limited search result without deep profiling of the particular file. The file system doesn’t manage repeated data files and update data files from different users either. This creates redundancy in the data system and increases storage usage. The file system categorizes data but doesn’t store it in desirable categories.

DBMS projects using SQL involve creating and managing databases through the Structured Query Language (SQL), which is used to handle organized data involving operations such as querying, updating, and administration of databases. These projects typically involve tasks like schema design, data normalization, writing complex queries, and implementing security measures to manage data effectively within a relational database system.

DBMS projects using MySQL involve utilizing the MySQL database management system to create and manage databases. MySQL is a popular open-source relational database system that uses SQL for database creation, modification, and querying. Projects can include designing database schemas, developing web applications with database backends, or setting up MySQL databases for handling large datasets and ensuring data integrity and performance optimization.

Advantages of DBMS

There are some following reasons to learn DBMS:

Organizing and management of data: DBMS helps in managing large amounts of data in an organized manner. It provides features like create, edit, delete, and read.
Data Security: DBMS provides Security to the data from the unauthorized person.
Improved decision-making: From stored data in the database we can generate graphs, reports, and many visualizations which helps in decision-making.
Consistency: In a traditional database model all things are manual or inconsistent, but DBMS enables to automation of the operations by queries.

FAQs on Database Management System(DBMS)

Q.1 what is database.

A database is a collection of organized data which can easily be created, updated, accessed, and managed. Records are kept maintained in tables or objects. A tuple (row) represents a single entry in a table. DBMS manipulates data from the database in the form of queries given by the user.

Q.2 What are different languages present in DBMS?

DDL (Data Definition Language) : These are the collection of commands which are required to define the database. E.g., CREATE, ALTER, RENAME, TRUNCATE, DROP, etc. DML (Data Manipulation Language) : These are the collection of commands which are required to manipulate the data stored in a database. E.g., SELECT, UPDATE, INSERT, DELETE, etc. DCL (Data Control Language) : These are the collection of commands which are dealt with the user permissions and controls of the database system. E.g, GRANT, and REVOKE. TCL (Transaction Control Language) : These are the collection of commands which are required to deal with the transaction of the database. E.g., COMMIT, ROLLBACK, and SAVEPOINT.

Q.3 What are the ACID properties in DBMS?

The full form of ACID is Atomicity, Consistency, Isolation, and Durability these are the properties of DBMS that ensure a safe and secure way of sharing data among multiple users. A – Atomic: All changes to the data must be performed successfully or not at all. C – Consistent: Data must be in a consistent state before and after the transaction. I – Isolated: No other process can change the data while the transaction is going on. D – Durable: The changes made by a transaction must persist.

Q.4 What are the Advantages of DBMS?

The followings are the few advantages of DBMS : Data Sharing: Data from the same database can be shared by multiple users at the same time. Integrity: It allows the data stored in an organized and refined manner. Data Independence: It allows changing the data structure without changing the composition of executing programs. Data Security: DBMS comes with the tools to make the storage and transfer of databases secure and reliable. Authentication and encryption are the tools used in DBMS for data security.

Introduction to RDBMS (Relational Database Management System)

In this article, I am going to give you a brief introduction to RDMB (Relational Database Management System) . Please read our previous article where we discussed Data Models in DBMS . At the end of this article, you will understand the following pointers in detail.

What is DBMS?

What is rdbms.

Features of RDBMS
Advantages of RDBMS
DBMS vs RDBMS
E.F. Codd’s Rules

DBMS is a software or group of programs designed to perform database operations such as creating a new database, administering and managing the databases by performing various user-specified database operations. The DBMS internally might consist of a group of programs each performing different tasks related to database management. Some DBMS examples, My SQL, Oracle, System 2000, MS Access, My SQL server, etc.

RDBMS is the collection of programs and capabilities that enables the user to interact with a relational database. A relational database management system (RDBMS) is a type of DBMS with a row-based table structure. Most commercial RDBMSes use SQL. The most basic RDBMS functions are related to create, read, update and delete operations, collectively known as the CRUD cycle.

Features of RDBMS:

An RDBMS is easily accessible using SQL commands.
An RDBMS provides full data independence.
The basic unit of data storage in a relational database is called a table.
A table consists of tuples/rows/records and each record has one or more columns used to store values.
In RDBMS, we can use conditional operations such as joins and restrictions.
An RDBMS enables data sharing between users.
Also at the same time, you can ensure consistency of data across multiple tables by using integrity constraints.
An RDBMS minimizes the redundancy of data.

Features of SQL:

High performance
High availability
Easy to learn and use
Robust transactional support
Functionally complete
Highly secure
Comprehensive application development
Management ease

How to communicate with RDBMS?

The structured query language is used to communicate with RDBMS.

Advantages of RDBMS:

Support for a very large database.
Automatic optimization of searching (when possible).
RDBMS has a simple view of the database that conforms to much of the data used in businesses.
RDBMS uses Structured Query Language.
Easy extendibility, as new data may be added without modifying existing records this is also known as scalability.
RDBMS has data security which is critical when data sharing is based on privacy.
RDBMS defines how the data is organized and how the relations among them are associated.
It defines the entities and relationships among them. It contains a descriptive detail of the database.

Disadvantages of RDBMS:

No support for complex objects such as documents, video, images.
Often poor support for storage of complex objects.
Still no efficient and effective integrated support.

DBMS vs RDBMS:

E.f. codd’s rules:.

Rule 1: The information Rule.

“This rule requires that all information should be represented as data values in the rows and columns of the table. This is the basis of the relational model.”

Rule 2: The Guaranteed access Rule.

“Each data value in a relational database should be accessible logically by specifying the relation’s name, primary key value, and the attribute name.”

Rule 3: Systematic treatment of null values.

“DBMS must support NULL values to represent missing or inapplicable information. NULL values must be distinct from zero or spaces. It must be independent of data type.”

Rule 4: Active online catalog based on the relational model.

“System catalog is a collection of relations that the DBMS maintains for its own use. These relations hold the description of the structure of the database.”

Rule 5: Comprehensive data sub-language Rule.

“This rule states that the system must support at least all of the following functions.”

Data Definition
View Definition
Data Manipulation Operation (Interactive and by program).
Security and Integrity Constraints
Transaction Management Operations

Rule 6: View updating Rule.

“All views which are theoretically updatable should be updatable by the system.”

Rule 7: High-level insert, update and delete.

“The rows should be treated as sets during insert, update and delete operation. The operation that modifies the database should deal with sets and not with single rows.”

Rule 8: Physical data independence Rule.

“The application programs must remain unchanged when any changes are made in storage representation or access methods.”

Rule 9: Logical data independence.

“The changes that do not modify any data stored in that relation, do not require changes to be made to the application program.”

Rule 10: Integrity independence Rule.

“Integrity constraints must be specified independently of application programs. They must be stored in the catalog.”

Rule 11: Distribution independence.

“Existing applications should operate successfully when the data is distributed. The physical location of data, the control program, and the application may be different but the distribution should not affect the functioning of the application.”

Rule 12: Non-subversion Rule.

“Database security and integrity should not be bypassed. The DBMS must ensure that no other level can bypass the constraints specified to maintain the integrity of the database.”

In the next article, I am going to discuss Why do we need database design? Here, in this article, I try to give you an overview of RDBMS (Relational Database Management System). I hope you enjoy this article.

What is a RDBMS (Relational Database Management System)?

DBMS Course - Master the Fundamentals and Advanced Concepts

RDBMS is an abbreviation for Relational Database Management System . It is a class of Database Management systems that emphasizes the relationships among data objects. Common types of RDBMS software examples are MySql , MariaDB , PostgreSQL , Oracle , SQL Server , etc.

A Brief History of RDBMS

The term "relational database" was invented at IBM by E. F. Codd in the 1 9 7 0 1970 1 9 7 0 . Four years later, IBM began the development of System R, a research project to develop a prototype RDBMS. The first RDBMS software sold was Multics Relational Data Store around June 1 9 7 6 1976 1 9 7 6 . In 1 9 7 9 1979 1 9 7 9 Oracle was released by Oracle Corporation, the then Relational Software. Some other examples of an RDBMS would be SAP Sybase ASE , IBM Db2 , Informix , etc. In 1 9 8 4 1984 1 9 8 4 the development of the first RDBMS for Macintosh code-named Silver Surfer, was released in 1 9 8 7 1987 1 9 8 7 as 4 t h 4th 4 t h Dimension.

Why Do We Need RDBMS?

Following are some major reasons for which Relational Database Management Systems are required :

Data Safety: Data is kept safe in an RDBMS when any of its programs(s) crash.
Fault Tolerance: RDBMS provides Fault Tolerance by replication of the database. This is helpful when the system crashes for some reason such as an accidental shutdown, sudden power cuts, etc.
RDBMS also facilitates concurrent access .
Ease of Use: While using RDBMS, accessing or managing the data becomes simple because of using tables for storing data in rows and columns.
Scalability: RDBMS can handle very small to very large amount quantities of data in a uniform fashion.
Indexing: In RDBMS indexes are used for sorting data which in turn speeds up performance.

Features of RDBMS

RDBMS represents data in simple logical constructs called tables or relations which are based on the set theory.
Each table (relation) is a set and thus we can manipulate each table using the rules of set theory such as union , intersection , etc.
This helps eliminate the parent chain hierarchy, thus representing data in a database as simple two-dimensional tables indexed by combinations of different rows and columns, in which are stored data values.
The objects of which we desire to store the data of, are stored in relations as rows that represent individual records, and columns that represent characteristics called attributes of the object.
A column, that represents the properties of an object, holds a value for every record in a certain format. These values must conform to the domain from which they were assigned.
Data in a relation may be retrieved by a query, which is a statement from a data language, which is a non-procedural language because it is not mandatory to specify the procedure that must be followed to get the work done.
Data Manipulation Language (DML) is the language used for manipulating the data stored in a database and consists of a set of instructions.

How Does RDBMS Work?

Following is an abstract representation of the working of a relational database management system :

Data Pages :

Disk accesses are slow, so vendors try to minimize them as much as possible. Data is divided into several pages of the same fixed size. When it is required to access data, a relational database will map the secondary-memory-based pages into primary memory buffers. When modification of the disk data is required, only the in-memory pages are altered by the relational database.

The disk-based pages are stored in the buffer pool which is of limited size. Therefore it usually requires storing the data working set. The buffer pool may store the entire data set, only if the memory accommodates it. If the data on the disk is bigger than the size of the buffer pool when a new page is to be cached, the buffer pool will evict old pages to make space for the new pages.

Since many concurrent transactions may access the in-memory changes, a concurrency control mechanism must be employed to ensure data integrity. Hence, once a transaction has altered any row of a table, the uncommitted changes are applied to the in-memory structures while the previous data is stored temporarily in an append-only undo log structure. If the currently executing transaction rolls back, the undo log will reconstruct the in-memory pages by the beginning of the transaction.

After a transaction has been committed, the in-memory changes must persist. We know, from the ACID transaction properties, that a committed transaction must provide durability, which indicates that all committed changes must persist. This is where the redo log comes into action.

It is also a disk-based append-only structure that holds every change done to a transaction. When a transaction is committed, all data page changes will be written to the redo log. In comparison to flushing a constant number of data pages, writing to the redo log is much faster because sequentially accessing the disk is faster than random access. Hence, it makes transactions fast.

Examples of RDBMS

Following are the names of some prominent RDBMS:

Oracle Database XE
SQLite (for mobiles)
SQL Server Express
Db2 Express-C

Uses of RDBMS

Following are the common uses of RDBMS:

Data Structure: Relationally storing data enables the database users to easily understand it, and provides simple origination of and access to data. Similar kinds of data may be stored within a relation.
Concurrent access to multiple users : RDBMS enables multiple users to simultaneously access a database. There exist inbuilt locking and transaction management mechanisms that allow these users to access data concurrently at which it also gets updated, thus preventing collisions between two users updating the data simultaneously, and also preventing users from accessing partially updated data.
Privileges: Features such as authorization and privilege control in an RDBMS permit the database administrator to grant privileges to certain users and restrict access to unauthorized users, based on the types of operations they desire to perform upon the database.
Network Access: An RDBMS provides access to a database through a server daemon. The server daemon is a special software program designed to listen for requests on a network and allows database clients to connect to a database and use it. Users need not necessarily physically log in to the computer system to be able to use the database, thus providing convenience to the users and security to the database.
Speed: The relational model though is not the fastest data structure, but its benefits such as simplicity, compensate fairly for the slow speed. Optimizations embedded into an RDBMS combined with the design of the databases, enhance performance and allow the RDBMS to perform sufficiently fast enough for most applications and data sets.
Maintenance: RDBMSs provide feature maintenance tools that provide database administrators with the means to easily test, maintain, backup, and repair the databases stored in the system. Many of these operations can be automated.

RDBMS Operators

1. select :.

Used for retrieving data from a database. Also supports filtering the retrieved data based on certain conditions.

2. PROJECT :

Produces a list of all the values for a selected attribute.

Links two different relations together, resulting in the creation of a new table.

Following are the different types of joins:

Natural JOIN: Links tables by selecting rows with common values in common attributes. It occurs in the following three stages :

The product creates a table.
Select yields appropriate rows.
The project yields a single copy of each attribute to eliminate duplicate columns.

Equi JOIN: Links tables based on equality conditions that compare specified attributes of tables.

Theta JOIN A version of Equi Join that compares specified attributes of every table using some operator other than equality.

How are RDBMS Structured?

A relational database includes:

System catalog: Tables that describe the physical conceptual structure of the data.
Configuration file: Contains the parameter values allocated for the database.

What is a Table/Relation?

In a relational database management system, a relation also referred to as a table, is a collection of data elements organized in a tabular form of rows and columns. Generally saying, a table may have duplicate data rows, while a true relation strictly prohibits having any such duplicity. The table is the simplest form of data storage.

Following is an example:

Properties of a Relation

The columns of a table represent the attributes/properties of an object. The rows of a table represent the values of different entries in relation, to different columns. Any row of any column can not have more than one value. There must not exist any duplicate rows in the same relation.

What is a Field?

Fields are the components of relationships that provide their structure. A table can not have zero fields, although a field may not have any value. Fields maintain relationships among tables, by creating matching fields in multiple tables. When creating a table or adding fields to an existing table, one defines the data type used for storing the data in each field. Occasionally, you may even mention the length of the field.

What is a Row/Record?

A row is also called a record . It is used for storing the value of a column for a particular instance (item). There might exist any number of rows as well as columns in a table.

Properties of a Row

Rows store values for columns. There should not exist any duplicate rows in a common relation. Different business objects may have different values for each column. Therefore we represent such as an object with a row.

What is a Column/Attribute?

A column is also referred to as an attribute. An attribute represents some property of an item, i.e. a table. Suppose we wish to create a table for storing information about cars. We will have to include the various properties of a car, such as color, number of wheels, brand name, etc. Each of these properties is represented in relation by relation with the help of attributes, or columns.

Properties of an Attribute

No two columns in the same relation should be the same. Different words store the values of a particular column for different business objects.

Attributes are also used for forming different types of keys in a relational database.

What is Data Item/Cells?

In a relation, data is present in tabular form, accessed by rows and columns. Each possible valid combination of a row and column in a relation, say ( i , j ) points to a cell. In a cell may be stored the value from a certain record, of a certain attribute.

The degree of a relation represents the number of entity types associated with the relation. For instance, suppose we have two entities, one is a child and the other is a toy and they are connected with the primary key and foreign key . Therefore the degree of this relationship is 2 since a total of 2 entities are associated in the relationship.

Types of Degree

Based on the number of linked entity types, the following are the four kinds of degrees of a relationship :

Cardinality

Cardinality represents the number of times an entity from an entity set participates in a relationship set. Or we restate the definition of cardinality as, the number of tuples in a relationship. Following are the 4 kinds of cardinalities in a relation :

One-to-many
Many-to-one
many-to-many

It is a unique set of values allowed for an attribute in a table. For instance, a domain of days_in_week will accept Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday as possible values.

NULL Values

A row may have no value set for a column. This absolute absence of an entry is known as a NULL value . It is to be noted that empty strings, zero, false, etc do not evaluate to null.

Data Integrity

Data integrity is the overall reliability , completeness , and accuracy of data. It may be specified by the lack of variation between two consecutive updates of a record. This implies that the information is correct and error-free. Data integrity also includes security and integrity controls and methods of regulatory compliance.

Data integrity is maintained by a list of validation and error-checking methods, principles, and rules exercised during the integration flow designing phase. These procedures are based on predefined business rules. The significance of preserving data integrity is when establishing relationships between disparate data elements, ensuring that the data sent from one stage to another is error-free and accurate.

Index in RDBMS

Indexing is used to optimize the performance of an RDBMS by minimizing the number of disk accesses required while query processing. An index is a data structure for quickly locating and accessing the data in a database. An index is created using two database columns.

The first column is the Search key and consists of a copy of the candidate key or the primary key of the relation. These values stored are sorted so that their corresponding data can be accessed quickly, although the data may not necessarily be stored sorted. The other column is for data referencing. It is a set of pointers, each of which holds the address of the disk block in which the particular key value should be found.

RDBMS Normalization

Normalization is A procedure for minimizing redundancy in a table. Redundancy in a table may cause deletion, update, and insertion anomalies. There are 5 levels of normalization, namely, 1nf , 2nf , 3nf , 4nf , and 5nf .

The Relational Model in RDBMS

The relational model in DBMS is an abstract model used to organize and manage the data stored in a database. It stores data in 2-dimensional inter-related tables, also known as relations in which each row represents an entity and each column represents the properties of the entity.

For further information on this topic have a look at this article on Scaler Topics.

RDBMS Extensions and Intensions

The extension of a relation is the set of rows appearing at any given instance in that relationship and thus varies with time. An extension thus changes as tuples are created, updated, and destroyed.

Following is an example :

Employee relation at t1 time :

Employee relation at t2 time after more records are added :

Employee relation at time = t2 after further adding records :

The intension of a relation is not dependent on time and is a permanent part of the relation corresponding to what is specified in the schema of the relation. All permissible extensions are hence defined by an intention. An intention comprises of the following two things: a set of integrity constraints, and a structure.

The structure contains the relation name and the names of the columns. The integrity constraints are divided into referential constraints , key constraints , etc.

For instance :

This is the intention of the Employee relation.

Advantages of RDBMS

Easy to use.
It is secure.
Data stored can be updated.
Limits redundancy and replication of the data. RDBMS offers data integrity and better physical data independence.
It offers logical database independence.
RDBMS provides backup and recovery procedures and multiple interfaces.
Multiple users may access a database in the relational model.

Disadvantages of RDBMS

RDBMS software is expensive , complex , and increases the overall cost of using a DBMS.
The operation of an RDBMS requires skilled human resources.
Certain applications using RDBMS are slow in processing.
In RDBMS, it is difficult to recover the lost data.

SQL Constraints

Constraints in SQL are the rules that we apply to the data types in a relation. We can specify the limit on the type of data that can be stored in a particular column in a table using these SQL constraints.

Following are the five constraints in SQL:

NOT NULL: It restricts the relationship to not store a null value in a particular column.
UNIQUE: When specified with a column, UNIQUE tells that all the values in the column have to be unique.
PRIMARY KEY: Among all candidate keys, a key is chosen to be the primary key. The primary key is used for virtually connecting one relation with another.
FOREIGN KEY: The primary key of the first relation will be exactly a copy of the foreign key, in terms of name, data types, and other characteristics. Now using the primary key from the first relation we can address the attributes in the other relation as if they were both a single relation.
CHECK: This constraint is used for validating the values of an attribute to satisfy a certain condition.
DEFAULT: This constraint puts a default value for the specific attribute when no value is given by the user.

ACID Properties and RDBMS

Relational DBMS follows ACID properties , which are as follows :

Either a transaction completes successfully, or it does not execute at all.

Consistency

The state of data in a database remains the same before and after a transaction.

Many transactions occur simultaneously, independent of each other, and without producing any interventions in each other.

The changes produced by a transaction reflect and persist in the database, even in the event of a failure occurring related to power, system, connectivity, etc.

The Relational Database of the Future: The Self-Driving Database

A database must store crucial information, essential for the efficient operation of a project. If the database is not protected, it might be subject to breaches, if it is slow and unavailable, it would not be of much use. This is self-driving (autonomous) databases come into the picture.

A self-driving DBMS is cloud-based and uses techniques such as AI to eliminate the manual effort required for database updates, tuning, backups, security, and other routine management tasks traditionally performed by database administrators.

Key Factors to Consider While Selecting an RDBMS

The most highly recognizable relational database management software is MySQL , which offers one of the most advanced and comprehensive features found in data management tools. It also provides users with one of the highest levels of security , scalability , uptime , and reliability .

Often termed as the most powerful RDBMS, the open-source PostgreSQL complies with the ACID properties . Postgres focuses on extensibility and has high reliability in storing data securely and returning it as a response to requests from other application software.

SQLite is a lightweight file-based embedded relational database management system that unlike most other RDBMS does not require its process, clustering, or user management. What makes SQLite lightweight while at the same time also retaining its relational power is that it uses an in-process compact library, which implements a serverless , self-contained , zero-configuration , and transactional SQL database engine .

An open-source, free, fully operational, and transactional database management solution for modern software development and enterprise use cases is MySql . The original MySql developers created MariaDB as a fork of the MySQL RDBMS after Oracle acquired MySQL in 2 0 0 8 2008 2 0 0 8 . MariaDB offers more database engines than MySQL itself does, for instance, BLACKHOLE , MyISAM , MEMORY , CSV , MERGE , etc. MariaDB’s backward compatibility is one of its strongest pros as a binary drop-in replacement for MySQL.

RDBMS vs DBMS

A DBMS is a software for systematically storing and managing data in a computer system. Examples, are MySql, MongoDB, etc. RDBMS is a specialized class of DBMS that is based on the concept of relational modeling.

Example: PostgreSQL, MariaDB, etc.

Entity in DBMS
What is the difference between DBMS and RDBMS?
RDBMS is a class of Database Management systems that emphasizes the relationships among data objects.
Needs of RDBMS: data safety, fault tolerance, concurrent access, ease of use, scalability, indexing.
Examples of RDBMS: MySQL, SQLite, MariaDB, PostgreSQL, SQL Server Express, Firebird, etc.
A relational database offers data consistency as it follows the ACID principles .

Combat impersonation using Face Check with Microsoft Entra Verified ID

Ankur patel.

June 5th, 2024 0 1

Combating fraud and impersonation with identity verification is essential in keeping any organization and its employee identities safe. A 2021 Microsoft survey of 3,000 US-based companies (with greater than 500 users), found that 92% of organizations today perform identity verification of some kind, but 82% of them wish there was a simpler, more secure way of verifying a remote user’s identity.

There aren’t many widely used methods that consistently and effectively verify who is using a company’s applications, which leaves the door open for impersonation. Most of the common methods of identity verification are ineffective or do not answer the right identification question.

Traditional passwords are supposed to verify who is attempting to gain access, but impersonators frequently exploit them. Microsoft detects over 4,000 password attacks per second , up from 1,287 in 2022.

Knowledge-based questions aren’t a reliable way of verifying identities either. The National Institute of Standards and Technology advises against using knowledge-based authentication because of how easily impersonators can discover or correctly guess the answers.

CAPTCHAs can identify that a human is attempting to log in rather than a bot, but they do not verify the identity of who is attempting to gain access.

Multi-factor authentication (MFA) can greatly reduce the risk of account compromise by identifying that the right device is attempting to gain entry, but a successful MFA does not guarantee the right person is using the device. Microsoft observed 6,000 MFA fatigue attacks per day in 2023 , so the threat of impersonators exploiting the human element of MFA is a common danger.

Organizations also need to prepare for new types of impersonation attacks with the increase of AI-assisted tools.

At Microsoft Build 2024, we demonstrated how Face Check with Microsoft Entra Verified ID introduces a high level of identity protection, with an intuitive, simple user experience. Read on to check out snippets from our Build demo and learn more about how to implement Face Check into your apps with Microsoft Entra Verified ID.

Are apps serving the right users?

How do we know that our apps are serving the right users without a consistently effective means of verifying who is attempting to use them?

In February 2024, we launched the public preview of Face Check , a premium feature within Microsoft Entra Verified ID that uses privacy-respecting facial matching, along with Verified ID verifiable credentials for high assurance verification.

Verifiable credentials provide a secure method for digitally verifying an individual’s identity, qualifications, or other attributes. Users own their credentials and store them in a digital wallet. For example, users can store their Verified IDs in the Microsoft Authenticator app. When asked to prove their identity, users can present their verifiable credentials.

Face Check for identity verification

Using just a verifiable credential is a great way to verify someone’s identity, but completing a Face Check adds an even higher level of assurance that the rightful credential owner is trying to gain access. Even if someone stole the credential owner’s phone and attempted to use their Verified ID to impersonate them, they could not bypass the Face Check verification. The Azure AI technology behind Face Check compares a live selfie against a trusted photo from the credential, making sure that only the Verified ID owner can complete a Face Check. It can also detect a wide variety of spoofing techniques, including deepfakes, and leverages years of learnings from operating Microsoft’s Windows Hello.

Face Check demos at Build 2024

Secure and streamline your help desk with face check.

Face Check with Microsoft Entra Verified ID can give your users an easy-to-follow identity verification experience that consistently protects their identity without sharing unnecessary personal data. At the 2024 Build conference, we shared a demo showing how Face Check can be used in a company’s help desk experience. Let’s walk through the scenario.

An employee wants to order a new laptop, change their password, or do something else through their company’s help desk. To do this, they must prove to the help desk that they are who they claim to be, and that they do actually work there. For many companies, this verification can potentially involve waiting for a long time to speak with someone at the help desk who can verify the employee’s identity in real time. Using the Face Check-powered help desk shown in the video below, an employee can quickly and conveniently verify their identity in real time:

Once the Face Check is completed, the verifier is given a confidence score which shows a percentage of how certain the person in the live selfie matches the person in the photo associated with the account. This value is the only data the verifier receives. Face Check does not store personal data and it does not give data to the verifier. A higher score means that the false-acceptance rate is lower.

Note: It is up to you as a developer to decide the acceptable threshold for the confidence score, depending on how sensitive the application is.

As a baseline, if the score is 90%, there is a one in a billion chance that the person in the live selfie is not the rightful credential owner. With statistics like that, you can be confident that only the right people will be able to access your company’s applications with Face Check.

Account recovery after total loss of credentials

What if an employee completely lost all employee credentials? In the case of a total loss, employees can still recover their account and regain access to their credentials. The Verified Help Desk can authenticate an employee’s identity with a Verified Government ID provided by leading identity verification providers, such as the ones listed in our partner gallery . Even without employee credentials, a user can quickly and securely recover their account.

Watch how employees can recover their account in the case of a total loss of credentials and perform the government ID verification in just a few clicks:

Add Face Check with Microsoft Entra Verified ID to your apps today

With identity threats growing more frequent and more complex every year, now is the time to enhance your identity protection with Face Check. Bring a critical layer of trust to your apps by introducing facial matching powered by Azure AI services.

Microsoft Entra Verified ID provides a seamless developer experience without compromising privacy or security.

To get started with Face Check, an admin must first set up Microsoft Entra Verified ID, which can be completed in a few minutes with this quick setup tutorial .

Once Verified ID is ready to use, you can easily add the requirement for a Face Check verification in the same request API. Start by having your application request that the user present a Verified ID for an application task, as it normally would without Face Check. In that presentation request, add three extra lines of code to the request to add the Face Check requirement.

The JSON payload to the  Request Service API  for creating a presentation request needs to specify that a Face Check should be performed. The claim containing the photo must be named and you may optionally specify your confidence threshold as an integer between 50-100. The default is 70.

If you are unfamiliar with how to create regular user requests for Verified ID verification, follow this tutorial .

Successful Face Check presentation_verified callback event

The JSON payload for the  presentation_verified has more data when a Face Check was successful during a Verified ID credential presentation. The faceCheck section is added which contains a matchConfidenceScore .

Note: It isn’t possible to request and receive the presentation receipt when the request includes faceCheck . There is a separate Face Check success/fail receipt.

Failed Face Check callback event

When the confidence score is lower than the threshold, the presentation request fails and a  presentation_error  is returned. The verifying application doesn’t get the score returned.

The Authenticator displays an error message informing the user that the confidence score failed to meet the threshold.

error code 403 - face not matched screenshot

Issuing a Verified ID credential with a photo

If a user already has their own Verified ID set up, it’s likely they already have a photo associated with the credential that their live selfie would be compared to in a Face Check verification.

If you want to learn how to set up a Verified ID with a photo, take a look at this tutorial . Below is the default Verified Employee data config for that credential.

The  display definition  for the photo claim should have the type set to image/jpg;base64u to let Microsoft Authenticator understand that it should be rendered as a photo correctly.

When setting the actual claim value of the photo, it should be in the format UrlEncode(Base64Encode(JPEG image)) .

Custom credential types using the  idTokenHint  attestation flow can also issue a Verified ID credential containing a photo. The credential definition needs to have the display and rules definition for the photo claim.

Securing your organization’s identities does not have to be complex. Microsoft Entra Verified ID allows you to quickly build unique user-owned identity scenarios that are designed for trustworthy, secure, and efficient interactions between people and organizations. Face Check provides an extra layer of certainty within those interactions that the right person is attempting to gain access to sensitive apps or resources.

Learn how to get started with Face Check with Microsoft Entra Verified ID and check out the latest Verified ID updates in the Microsoft Entra Verified ID developer center .
