Database in simplest words is a structured repository of data needed for the functioning (data processing) of an organization. A Database Management System (DBMS) is a collection of programs that enables users to create and maintain database. The DBMS is hence a general purpose software system that facilitates the process of defining, constructing, and manipulating databases for various applications.Defining a database involves specifying the data types, structures, and constraints for the data to be stored in the database. Constructing the database is the process of storing the data itself on some storage medium that is controlled by the DBMS. Manipulating a database includes such functions as querying the database to retrieve specific data, updating the database to reflect changes, and generating reports from the data.
