Business objects association models based on state log and association log
基于状态与关联日志的业务对象关联模型

It is important to build well-designed business model to realize fast reconfignration of enterprise information system in accordance with the business changes. Traditional business modeling methods can not effectively deal with complex association relationships between business objects; therefore extendibility, adaptability, second-round development efficiency and traceability of ESA are greatly influenced. To overcome this limitation, in this paper we presented a log-based business object association model, in which complex and volatile associations between objects were clearly separated from the inner structure of objects and the numerical association styles were discussed with emphasis. Business logics on objects were classified into two types, i.e., simple operation that dealt with inner logics in a simple object, and complex operation that dealt with numerical associations between objects. Run-time states of business objects and association information between objects were separated as logs for further traceability.
