基于业务规则的事件驱动建模方法

为使企业信息系统的分析与设计能有效管理业务逻辑的高度复杂性，适应业务环境的易变性，该文在结构化分析与面向对象设计方法的基础上提出一种复合型的业务过程建模方法。其指导思想是将事件驱动的业务规则作为贯穿建模过程的主线，同时引入业务对象的参考模型，能更深刻地揭示系统内部组成单元的动态交互特性，并增加对象识别与提炼的规范性。此外，还运用分布式对象技术和组件技术规划了企业应用程序与业务对象的运行模式。由于业务知识被作为可更改的规则封装在分布式对象服务器的内部，从而可为信息系统的重构和再配置提供有力支持。

Event-driven approach with business rule-based modeling

In order for the enterprise information systems to efficiently cope with the highly complexity of business logic and to be adapted to the mutabilty of business environment, based on the structural analysis and object oriented design methodology, a hybrid modeling approach is proposed for business processes. The event driven business rules as a backbone of modeling process, with the help of the reference models of business objects, can reveal the dynamic interaction properties of system composite units more thoroughly and guide objects specification and abstraction more formally. Besides, the executing pattern of enterprise application and business objects are outined in terms of the distributed objects and componentware technologies. The fact that the business knowledge are encapsulated as built in rules of the distributed object servers can provide powerful supports for the reconstruction and reconfiguration of information systems.
