The DBMS is located at the core of most database applications. There are database servers that can hold the actual databases and run only the application as well as related software. DBMS is usually built around the custom multi tasking kernel that can support numerous networks.
The software is composed of DBMS engine wherein it has the ability to accept request from the subsystems and change then into physical equivalent. Data definition subsystem is the component in which it helps the users to generate and maintain data dictionary and define the composition of the file in a certain database. Data manipulation subsystem allows the users to add, change, delete information in the database and question it to gain information.
