Referential integrity in databases ensures the consistency and accuracy of data relationships between tables. It prevents situations like orphaned records and invalid relationships, maintaining data accuracy and integrity. It works by enforcing rules that ensure data relationships are valid, such as ensuring that every foreign key value corresponds to a valid primary key value in the referenced table. By enforcing these rules, referential integrity safeguards against data inconsistencies, improves data quality, and enhances the overall reliability and efficiency of the database.
