Answer: Referential integrity can be ensured by utilising primary and foreign keys, For references across tables to always be valid, each foreign key needs to match a main key.
Referential Integrity.
- It is a property of data that all of its references are legitimate, which is known as referential integrity.
- A value of one attribute (column) of a relation (table) must exist if it refers a value of another attribute in the context of relational databases.
- Every time a foreign key value is used, it has to refer to a legit, already- existing primary key in the parent table. Referential integrity, for instance, might be violated by removing a record that contains a value that is referenced by a foreign key in another table.
- Some Relational database management systems (RDBMS) have the ability to enforce referential integrity. Usually, this is done by deleting the rows associated with foreign keys in order to preserve integrity.
