 What is Database Management System

Introduction:-

                           A database management system (DBMS) refers to the technology for creating and managing databases.  DBMS is a software tool to organize (Create, Retrieve, Update and Manage) data in a database.

2) Data independence and efficient use of data.

3) For uniform data administration.

4) For concurrent access to data, and data recovery from crashes.

5) To use user friendly declarative query language.
