Referential integrity constraint - The referential integrity constraint is specified between two relations and is used to maintain the consistency among tuples of the two relations. A tuple in one relation that refers to another relation must refer to an existing tuple in that relation. 
For example, the value of attribute DNO in every EMPLOYEE tuple must match the DNUMBER value of some tuple in the DEPARTMENT relation.
