摘　　要：对于大多数主动数据库来说,复合事件监测始终是个难题。介绍信息网模型INM(Information Network Model)数据库管理系统中的复合事件监测机制,详细描述利用事件树模型监测复合事件的思想,并提供具体的算法实现。经分析,该算法在运行效率和空间占用上均比常见的有限自动机和Petri网有着更好的表现。For most active database system, it, s difficult to detect composite event. The paper introduces the composite event detectingmechanism in I N M D B management system, describes in detail the idea of using event tree model to detect composite events, and providesspecific algorithmic implementation as well. According to the analysis, this algorithm is better than finite automaton and Petri nets, which aremuc h more c o m m o n , in both running efficiency and memory occupation.
