摘要： 给出了基于主动规则——ECAP(event-condition-action-parameter)规则的分层应用系统的框架和运行机制,用ECAP规则来描述应用程序的业务逻辑,完成过程组件的调用。通过修改ECAP规则和相关基本对象及其数据端口,有效而灵活地完成系统的重构。并以图书馆采访子系统为例,运用ECAP规则进行设计。

Abstract: The framework and the operation mechanism for hierarchy application system based on active rulesECAP rules are presented. ECAP rules are used to express the business logic and to call these components. Through modifying the ECAP rules and the dataports of hierarchy components , we can reconstruct the system effectively and flexibly. Then it shows an example of how to apply the technology to design the sub-system of the library management system.
