摘要:现代信息技术的发展使得教育系统中的主动式数据服务开始成为热点。借助主动数据服务,系
统管理人员可以设置主动规则(ECA 规则)使数据库独立地管理信息。针对校园应用的特点,可以对
ECA 规则进行扩展,使得扩展后的规则(X-ECA)可以使用相同的模型对不同事件或操作进行抽象。此
外,这种基于 X-ECA 的架构能够以组件形式与现有应用衔接,避免了繁琐的部署流程。

Abstract: The ever-developing modern information technology is getting the research on active data service
hot in the field of education. Using such kind of service, it’s possible for the system administrators to enable
database systems to manage information independently by setting active rules (ECA). According to the
features of campus information applications, another active rule language (X-ECA), which derives from ECA,
has been proposed to describe different events or operations in the same model. In addition, this X-ECA based
architecture is able to connect with current applications loosely as an ponent, which getting rid of so
much boring task when deploying this function.
