Referential integrity enforces a relationship between two tables by ensuring that a foreign key in one table matches a valid primary key in another table. This constraint guarantees that the data is consistent and prevents "orphan" records. For example, in an "Orders" table with a foreign key referencing a "Customers" table, referential integrity ensures that every order must belong to an existing customer. If a foreign key value does not match any primary key value in the referenced table, the database system will reject the operation, ensuring data consistency. Why Other Options Are Incorrect:
