A database management system (DBMS) is a software package designed to
define, manipulate, retrieve and manage data in a database. A DBMS generally
manipulates the data itself, the data format, field names, record structure and
file structure. It also defines rules to validate and manipulate this data. A database is the back-end of an application. A DBMS
receives instruction from a database administrator (DBA) and accordingly
instructs the system to make the necessary changes. These commands can be to
load, retrieve or modify existing data from the system. A DBMS always provides
data independence. Any change in storage mechanism and formats are performed
without modifying the entire application.
