Integrity constraints form an important part of a data model. Therefore, a complete integrity constraint handling subsystem is considered an important part of any modern DBMS. In implementing an integrity constraint handling subsystem, there are two major problem areas: providing enough functionality and delivering good performance in constraint enforcement. In the PRISMA project, an integrity constraint handling subsystem for a relational DBMS is developed, that meets both requirements. Functionality is reached through a modular and extensible architecture of the subsystem. Performance is reached through extensive use of parallelism in various constraint enforcement algorithms.
