摘要
通过运用网格技术,建立一个分布式,海量的教育资源库,为远程教育过程中的用户提供一个高效数据共享、有效管理的虚拟教学信息空间.远程教育网格使用网络服务描述语言(WSDL)对系统服务进行描述,结合学习对象的概念和远程教育的特点,分别定义了三种网格服务:学习对象存储服务、学习对象检索查询服务和学习对象注册服务.通过在Linux多机环境下搭建一个用户注册-登陆-使用-注销的测试环境,对远程教育网格的基本工作流程进行测试.
As a typical case of information service grid in educational area, e-learning grid adopts grid technology to setup a distributed mass educational resource environment. Distance learning users treat this as a high data sharable and effective manageable virtual educational space. E-learning grid uses WSDL ((W)eb (S)ervice (D)escription (L)anguage) to describe system service. Combining the concept of Learning-Objects (LOs) and characteristic of distance learning, system defines three grid services: LOs Repository service, LOs Storage-Retrieval service, LOs Registry service. An experimental system with Linux multi-host of e-learning grid, which provides the service of user register-login-usage-logout, illuminates the basic flow of e-learning grid.
