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.
The work reported in this document was conducted as part of the PRISMA project, a joint effort with Philips Research Laboratories Eindhoven, partially supported by the Dutch "Stimuleringsprojectteam Informaticaonderzoek (SPIN)"
