Purpose of DBMS

The standard acronym for database management system is DBMS, so you will often see this
instead of the full name. The ultimate purpose of a database management system
is to store and transform data into information to support making decisions.

A DBMS is a software for creating and managing
databases. It provides users with a systematic way to create, retrieve, update
and manage data. It is a middleware between the database which store all the
data and the users or applications which need to interact with that stored
database. A DBMS can limit what data the end user sees, as well as how that end
user can view the data, providing many views of a single database schema.
Organizations use large amounts of data. A database management system (DBMS) is a software tool that makes it
possible to organize data in a database.
A DBMS consists of the following three elements:
1.     
The physical database: The collection of files that contain the data
2.     
The database engine: The software that makes it possible to access
and modify the contents of the database
3.     
The database
scheme
: The
specification of the logical structure of the data stored in the database
