摘要
对于主动实时数据库中复合事件的探测，提出了“复合事件表达式”描述方法和用“状态自动机”处理的方法，包括用算符优先法对复合事件表达式进行预处理。
The active real time database system ARTs II is possessed of correctness, timeliness and activeness. Its active mechanism is a trigger mechanism. The executions of triggers depend on the detection and handling of the event, especially of the composite event. A method of handling the composite event by the state automaton, based on the “composite event expression”, including the pre processing of the composite event expression by the operator precedence method, the handling of elementary composite operations, and the state transfers of the state transition matrix of the composite event based on elementary events, is proposed.
