Abstract

Active database systems must provide efficient support for event detection and rule execution. Large applications that benefit from facilities offered by active database systems require tools for their whole life cycle — otherwise there will be no acceptance of this new database technology. Therefore, we propose to extend the well-known and broadly accepted OMT design methodology to model classes and rules which have to be mapped onto a rule language. Then we present the rule languages of NAOS, SAMOS, and REACH and compare them from a user's point of view. To improve the rule management REACH offers the facility to organize rules in so-called rule directories which provide a structured name space like UNIX directories for the storage of files. Then we describe a comprehensive set of commands for rules and rule directories, especially an access control mechanism for rules. Additionally browsers for the rules, the rule triggering graph, and the event history are presented, and finally we show how the triggering of rules within applications can be visualized online in a trace mode.

This work is sponsored in part by the ACT-NET research network on active databases which is part of the program ”Human Capital and Mobility” of the European Union.
