No software can be build without database.
Let us now see what is a databse and how the database works.
1. What is a data?
A data is a collection of organised information.

The structured collection of data is called database.

3. What is Database Management System[DBMS]?
DBMS is a system or software which manages the databases.
DBMS uses different types of data models like hierarchial,network,relational and
object model for designing the databases.
