Database Management system:-
A Database Management System (DBMS) is a software system that enables users to define, create, maintain, and control access to a database. It allows users to store, modify, and extract information from a database as needed. A DBMS typically provides a secure, robust environment for storing and managing large volumes of structured and unstructured data. It also provides an efficient way to access and manipulate data stored in a database. It can also be used to enforce data integrity, security, and data consistency.
