Parallel handling of integrity constraints

Abstract: 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 PIt.ISMA project, an integrity constraint handling subsystem for a relational DBMS is developed, that meets both requirements. Functionality is rea… Show more

“…In the PRISMA project this approach is taken [44]. The parallel data management layer of the PRISMA database system is equipped with a special-purpose interface for the specification of certain kinds of constraints that can be enforced more or less autonomously by this layer as part of the two-phase commit protocol.…”
