中小学数字校园应用系统的集成研究

Research on the Integration of Digital Campus Application System in Primary and Secondary School

为解决中小学数字校园建设中的"信息孤岛"问题,文章首先分析了多平台间的数据存储技术和多种数据交换模型,然后提出要采用基于SOA(Service-oriented Architecture)的数据交换模型与CAS(Central Authentication Service)、LRS(Learning Restore System)相结合的集成技术。文章构建了基于SOA的多平台信息融通数字校园架构,并在中小学数字校园Eschool集成系统上解决了平台间的数据交换、权限分配和角色转换等实际问题。

In order to solve the ＂information island＂ problem of digital campus construction in primary and middle schools, this paper firstly analyzed the multi-platform data storage technology and data exchange model, then proposed to adopt the integrated technology that combined data exchange model based on SOA（Service-oriented Architecture）, CAS（Central Authentication Service）, and LRS（Learning Restore System）. This paper constructed a digital campus architecture with multi-platform information circulation based on SOA, and solved the practical problems of data exchange, access assignment and role transfer in the Eschool integrated system of digital campus.
