Active database system has been introduced to extend the database functionality. It is capable of detecting specific events and automatically reacting to them by executing certain actions either inside or outside the database. This behavior is usually specified through Event Condition Action (ECA) rules. Rule design plays a critical role in implementing an active database system, it is not always straightforward due to lack of methodology. In this paper is presented a new approach to identify ECA rules that could strongly express application semantics. Additionally is proposed an ensemble method for triggering more appropriate ECA rules when the interesting events occurred.
