integrity constraint

<database> A constraint (rule) that must remain true for a database to preserve data integrity. Integrity constraints are specified at database creation time and enforced by the database management system.

Examples from a genealogical database would be that every individual must be their parent's child or that they can have no more than two natural parents.
