A database management system (DBMS) is the software that allows a computer to store, retrieve, add, delete, and modify data. A DBMS manages all primary aspects of a database, including data manipulation management, such as user authentication, as well as data insertion or retrieval. A DBMS defines what is called the data schema or the structure in which the data is stored.
The tools we all use on a daily basis require DBMS behind the scenes. This includes automated teller machines, flight reservation systems, retail inventory systems and library catalogs, for example.
Why use database management system?
The DBMS manages three important things: the data, the database engine that accesses, locks and modifies data, and the database schema, which defines the logical structure of the database. . These three fundamentals help ensure concurrency, security, data integrity and consistency of administrative procedures.
