越来越多的大学正逐步把现有的网络课程平台向教育云服务平台过渡,实际上这是一个网络课程系统再工程的过程。在保持原有网络课程系统主要功能的基础上,移植原系统所使用的框架和重构原系统的数据访问层,采用GoogleApp Engine、Google Web Toolkit和Ext-GWT等技术并结合面向服务开发方式,我们成功地实施了把传统技术开发的网络课程再工程到Google云计算平台。随着Google App Engine SDK的不断完善,会有越来越多的优秀框架陆续受到支持,从而降低再工程的难度。

More and more universities are updating their online course system to Cloud-based Education Service,which actually is a re-engineering of online course system.To port the frame and redactor the data access layer of the existing system,we use Google App Engine,Google Web Toolkit and Ext-GWT with service-oriented design.As a result,we successfully port the traditional online course system to Google Cloud Computing Platform.It is proved that service-oriented developing style Google Cloud Computing Service provided is a scientific way to develop ＂Cloud-based Education Service＂.It has the key functions that future ＂Cloud-based Education Service＂ requires.If Cloud Computing platform supports more and more traditional frameworks,less and less effort will be made to reengineer the online course system.
