Design and implementation of Chimera active rule language

摘要

This paper describes the implementation of active rules in the Chimera object-oriented database system. The Chimera active rule language is very rich, since it provides alternative semantics for active rules and combines several innovative features. We show how a run-time support for that active rule language is designed and implemented through the necessary data structures, functional components and algorithms. The paper also compares Chimera active rule implementation with other active database system implementations.
