摘要
实时数据库系统的基本要求是系统具有描述和实施事务时限的能力。本文给出实时数据库系统中的触发器机制，使系统具有实施时限的能力，同时具有主动性。文中详细讨论了触发器的结构和探测器、监控器的实现原理。
An real-time database management system is characterized by its ability to describe and enforce time-constraints of transactions.In this paper,a trigger mechanism for real-time database system is presented.The system have abilities to enforce time-constraints and activate.We discuss in detal the structure of trigger and the imple mentation method for detector and monitor.
