基于状态与关联日志的业务对象关联模型

构造良好的业务模型是实现企业信息系统快速重构以适应业务变化的关键。传统的业务建模方法对业务对象之间存在的复杂关联关系无法有效解决，对系统的可扩展性、二次开发效率、追溯性等方面有较大影响。为了解决此问题，提出了一种基于日志的业务对象关联模型，将对象间关联关系与业务对象清晰分离开来，重点探讨了业务对象间数值关联方式，采用简单操作来处理对象内部业务逻辑，采用复合操作来处理对象间关联关系，并将运行时的对象状态与关联信息分离出来形成日志，进而实现基于日志的业务追溯。

Business objects association models based on state log and association log

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.
