Integrity constraints are a means to model the quality of databases. Measures that size the amount of constraint violations are a means to monitor and maintain the quality of databases. We present and discuss new violation measures that refine and go beyond previous inconsistency measures. They serve to check updates for integrity preservation and to repair violations in an inconsistency-tolerant manner.
