摘要
通过引入一元时序算子 ,表达事件之间任意复杂的相对次序关系 ,在此基础上重新定义了描述复合事件的时序事件代数 ,并证明了该事件代数良好的数学性质 .不仅增强了事件描述语言的描述能力 ,也为处理规则执行的合流性提供了新的方法 .
By introducing unary temporal operators, any complicated relative sequential relations among events can be modeled. Based on this, a temporal event algebra for modeling composite events is redefined, along with it's mathematical properties being proven. This not only enriches the expressive power of the event language, but also provides a new approach to confluent rule execution in active database systems.
