摘要
元数据标准是实现数据有效管理、共享、交互的一种重要手段。通过对高校信息化建设的现状和面临的问题进行分析和研究,提出了一个基于元数据标准的信息集成模型。此模型通过使用统一的元数据标准和对元数据的存储管理,屏蔽了各种数据源的异构性,实现了各个应用系统之间数据的共享与交互。
The standard of metadata is one of the most important methods to manage,share and exchange data.This paper analyzes current situations and problems of the integration of campus,and proposes a new model of information integration which is based on the standard of metadata and the storage of the metadata.It can shield the heterogeneity of the various data sources,and finally be helpful to share and exchange informations between different application systems.
