Definition
Noun: A Database Management System (DBMS) is a software system designed to facilitate the creation, organization, maintenance, and controlled use of an electronic database. It serves as an intermediary between the database itself and the users or application programs, managing how data is stored, retrieved, secured, and manipulated.
Usage
A DBMS provides a systematic way for users and software to: * Create and define a new database and its structure. * Insert, update, delete, and retrieve data from the database. * Maintain data integrity and security through access controls. * Manage concurrent access by multiple users to prevent conflicts. * Back up and recover data.
Examples
- "The company uses a relational DBMS to manage its customer records and transaction history."

Advanced Usage
