The architecture and the implementation of the active, object- oriented database management system SAMOS are described. SAMOS is a research prototype extending a commercial object-oriented database management system with reactive behavior specified in the form of event- condition rules. This paper describes the various components of SAMOS for event detection, rule management, rule execution, and transaction management, and explains how they work and interact upon rule definition and execution. The current architecture of SAMOS is evaluated, experiences with the layered approach are described, and drawbacks are identified.
