Abstract
Integrity constraints (or simply “constraints”) are formal representations of invariant conditions for the semantic correctness of database records. Constraints can be expressed in declarative languages such as datalog, predicate logic, or SQL. This article highlights the historical background of integrity constraints and the essential features of their simplified incremental evaluation. It concludes with an outlook on future trends.

Inconsistency-Tolerant Integrity Checking
Property of simplification methods that makes them usable also in the presence of inconsistency. Whenever an inconsistency-tolerant method returns that integrity is satisfied, the preservation of all consistent cases of the integrity theory in the updated state is guaranteed even if there were inconsistent cases before the update.
