摘要
解决数字校园建设中存在的大量异构数据集成问题是目前教育信息化过程中的关键.针对异构数据导致的信息与资源分散,管理成本高,决策支持弱,网络基础服务平台与应用系统脱节等问题,提出了一种数字校园的异构数据集成方案数字校园公共平台.然后根据数字校园公共平台的体系结构,详细描述了分层设计的体系结构的各层内容,给出了全局数据库模型建立、数字校园公共平台架构和统一数据访问等关键技术的实现.
In the development of education information, the key point is to solve the issue of numerous heterogeneous data integration existing in the construction of digital campus. A scheme of heterogeneous data integration on the digital campus -- digital campus common platform （DCCP） was presented in terms of the decentralization of information and resource resulted from the heterogeneous data, high handling cost, weak decision- making support and the network basic service platform coming apart from the application systems and other issues. And then the contents of each layer of hierarchical design architecture was depicted, the database model of the whole area and the implementation of DCCP structure, universal data access and other key techniques were given, based on the platform＇s architecture.
