Referential integrity:
Referential integrity is a concept in database theory that ensures data integrity by enforcing a link between related tables in a relational database. It requires that if an entry in one table contains a foreign key that references an entry in another table, the referenced entry must exist in the second table. This ensures that the link between the two tables is maintained and that data is not lost or corrupted. It also prevents duplicate entries from being created in the second table. Referential integrity is a fundamental concept of database theory and is essential for maintaining the integrity of data in a relational database.
