摘要：

Integrity constraints represent a method of ensuring that database updates do not result in data inconsistencies. For business applications in particular, the accuracy of the data is important. Therefore, we need strong guarantees that the information stored in the database system is not tempered with. This paper presents some algorithms for testing the integrity constraints given by the functional, join and multivalued dependencies. Since the update operations are costly, the algorithms described take into consideration efficiency requirements.
