DATABASE MANAGEMENT SYSTEM
Database is a collection of related data and data is a collection of facts and figures that can be processed to produce information.
Mostly data represents recordable facts. Data aids in producing information, which is based on facts. For example, if we have data about marks obtained by all students, we can then conclude about toppers and average marks.
A database management system stores data in such a way that it becomes easier to retrieve, manipulate, and produce information.
