Using Active Database Techniques for an Advanced Alarm Processing

摘要

An Advanced Alarm System (AAS) is primarily a digital system employing advanced alarm process logics and a VDU (Visual Display Unit) based control and display for the alarms. Active Database Systems (ADSs) are able to monitor a special situation represented by an event and one or more conditions. When the event occurs and the conditions are evaluated as true, the corresponding actions are executed. Hence, ADSs can recognize specific situations and react to them without direct explicit user or application requests. ADSs are very useful for timely applications such as the advanced alarm processing. This paper proposes a new approach to the advanced alarm processing by using Event-Condition-Action (ECA) rules that can be automatically triggered by an active database. And this paper describes the design considerations and solution plan for advanced alarm processing by using active datbase techniques.
