What will be an ideal response?
A database is a collection of related data that is stored and organized in a manner that enables information to be retrieved as needed. Database software-more formally called a database management system (DBMS)-is used to create,maintain, and access a database. A DBMS also controls the organization of the data and protects the integrity and security of the data so it is entered accurately into the database and then protected against both intentional and accidental damage. While batch processing can be used with databases, most database applications today occur in real time.
