Referential Integrity Is Important For Databases
November 17, 2005 Abstract: Referential integrity is a database constraint that ensures that references between data are indeed valid and intact. Referential integrity is a fundamental principle of database theory and arises from the notion that a database should not only store data, but should actively seek to ensure its quality. The notion of referential integrity also applies to OODBMSs. There are relationships between objects that cause them to depend on each other and maintenance of these dependencies should not be left to application code.
