A rule repository for active database systems

Abstract

Active Database Systems (ADBSs) provides a good infrastructure to define and execute active rules. Nevertheless, this infrastructure offered by ADBSs does not completely satisfy the necessities of rules management that demands current business applications. Rules also need to be stored in appropriate structures to facilitate their management, as the existing structures for data in these systems. This work proposes a rule repository, composed by structures that allow the storage and organization of rules, in order to facilitate their management. For this purpose, a rule classification with the main rule types existing in the literature is presented, and then, it represents the characteristics and anatomy of each type in a meta-model, with the goal of analyzing the data that must be stored about rules. The rule repository, proposed in this paper, has been built based on this meta-model.
