基于元数据仓储的数字图书馆检索服务系统开发研究

Research on the development of digital library retrieval service system based on metadata storage

文章介绍了基于联邦数据库系统的和基于数据仓储的两种数据整合的方式,并进行了横向比对,对本文采用的元数据仓储进行了详细阐述,基于元数据仓储方式下介绍了数字图书馆建设中Oracle数据库、Tomcat服务器和MD5算法三大技术支持。文章以某数字图书馆系统建设为依托,从元数据存储设计入手,介绍了系统完成后的各项功能,对其他图书馆的数字建设工作提供了宝贵经验。

This paper introduces two methods of data integration based on federated database system and data warehousing,and makes a horizontal comparison.The metadata warehousing used in this paper is elaborated in detail.Based on metadata warehousing,the paper introduces three major technical supports of Oracle database,Tomcat server and MD5 algorithm in the construction of digital library.Based on the construction of a digital library system and the design of metadata storage,this paper introduces the functions of the system after completion,and provides valuable experience for the digital construction of other libraries.
