摘要
数字图书馆如何将已有数字资源有效地整合在一起,更好地为用户服务,成为当前亟待解决的问题.数据集成是解决这一问题的有效方法.论文首先对数字图书馆面临的异构数据集成问题进行分析,在参考国内外关于异构数据集成的最新研究成果基础上,针对军事训练数字图书馆的特点,提出构建以数据仓库为核心的数据集成平台,然后设计并实现了一个基于Microsoft.NET平台,以数据仓库为核心和XML为数据交换格式的适合于军事训练数字图书馆的五层模型数据集成架构.
It is a challenge to integrate digital resources of library efficiently for providing better services to users when building digital library. Data integration should be an effective solution of this question. This dissertation mainly analyzes the architecture of heterogeneous data integration of the Military Training Digital Library （ MTDL）. After studying specialties of the MTDL and referring to the achievements of heterogeneous data integration at home and abroad, the thesis proposes the use of data warehouse as the core for building architecture of heterogeneous data integration. The author designed and realized a practical architecture satisfying the needs of the MTDL. It is based on Microsoft . NET platform, using data warehouse as core, and taking XML as data transform format.
