具有集中索引的数字图书馆系统结构

An Architecture with Master Index for Digital Libraryies

数字图书馆是基于Internet的分布式信息系统 ,结构设计是影响系统可靠性和性能的关键因素之一。本文描述数字图书馆系统的基本结构 ,通过实例阐述并分析了“完全的分布式结构”和“集中索引的分布式结构”两种数字图书馆系统结构设计。“集中索引的分布式结构”

Digital library is a distributed information system based on the Internet,its architecture design is one of the key factors that affect the system reliability and performance.This article describes the general architecture for the digital library,and discusses and analyses two kinds of architecture which are Fully Distributed System Architecture and An Architecture with Master Index for Digital Library through case studies.An Architecture with Master Index for Digital Libraries can provide better system reliability and performance than Fully Distributed System Architecture can do.
