SICSDD: Techniques and implementation

Abstract

This paper presents the constituent techniques and the implementation of a semantic integrity subsystem for a distributed database (SICSDD). The subsystem provides complete functionality and an efficient strategy for constraint enforcement. Complete functionality is attained through a modular and extensible architecture in which several techniques are incorporated. These are either modifications/extensions of techniques developed by other researchers or new techniques proposed by us. The integration of these techniques is necessary to achieve efficient constraint enforcement, particularly in a distributed database.
