摘要
在OCL和ECA规则的基础上,通过对业务对象与ECA规则的时态化关系的分析,提出了业务规则与约束的一种时态化扩展建模方法,该方法引入了时态化算子和时间区间等概念来实现对时态化对象和属性的历史信息的引用和时态化建模。
Based on Object Constraint Language （OCL） and Event Condition Action （ECA）, a temporal extending method was proposed for enterprise business rules and constraints, which used temporal operators and time intervals to refer to history information of temporal objects and temporal properties. The relationship between business objects and ECA rules was also analyzod.
