A DBMS makes it possible for end users to create, read, update and delete data in a database. The DBMS essentially serves as an interface between the database and end users or application programs , ensuring that data is consistently organized and remains easily accessible.The DBMS manages three important things: the data, the database engine that allows data to be accessed, locked and modified -- and the database schema , which defines the database’s logical structure. These three foundation elements help provide concurrency , security, data integrity and uniform administration procedures.
