Database Management System

A Database Management System (DBMS) is a software system designed to store, retrieve, define, and manage data in a database. It acts as an intermediary between users or applications and the database, facilitating organized and efficient data handling. DBMS plays a crucial role in ensuring data consistency, integrity, and security across various applications.

Key functionalities of a DBMS include:

    
• Data Definition: Allows users to define the data types, structures, and constraints for the data to be stored in the database.
    
• Data Manipulation: Enables operations such as inserting, deleting, updating, and querying data.
    
• Data Security and Integrity: Provides mechanisms to control access to data and ensure that the data remains consistent and correct.
    
• Data Storage Management: Manages how data is stored on disk and accessed.
    
• Backup and Recovery: Offers tools to back up the database and recover data in the event of system failures or data loss.

Popular examples of DBMS include MySQL, Oracle Database, Microsoft SQL Server, PostgreSQL, and MongoDB. The tables presented in the question (Table-1 and Table-2) represent structured data that would typically be managed and organized within a database using a DBMS.
