Database integrity

Database Integrity: Database integrity is to ensure that data entered in the database is accurate and valid. Means that if there is any rule applied to any entity.. the entered data must obey that rule.

For Example: 1) If datatype is selected number so no alphabet and other symbols can be inserted to that attribute. 2) If there is a domain integrity is defined so DB integrity is to ensure that entered data must belong to the defined domain integrity...
