What role does referential integrity play in data integrity testing?
- Ensuring proper indexing of database tables
- Ensuring that all foreign key constraints are properly defined and maintained
- Validating user permissions
- Verifying the performance of database transactions
Referential integrity ensures that relationships between tables are enforced through foreign key constraints. It guarantees that all foreign key values in a table reference an existing primary key in another table. By maintaining this relationship, referential integrity helps maintain data consistency and accuracy, which are essential aspects of data integrity testing. Thus, it plays a crucial role in ensuring the integrity of the data within a database.
