Abstract
This paper presents an architecture of a component based active mechanism suitable for federated database systems (FDBMS), i.e., a collection of autonomous DBMS with a common understanding of their universe of discourse. The main components of the mechanism are flexible event and rule services that cooperate to execute active rules. The event service allows the specification and generation of event managers that detect, produce and notify events using an event management model. The rule service manages Event-Condition-Action rules global to federated database systems. Rules are triggered by events notified by event managers. Conditions and actions can concern multiple DBMS. The execution model of a rule is adaptable to the different component DBMS characteristics.
