【摘要】 本文主要讨论了采用Web服务技术实现校园网内部异构资源平台间的共享问题，以首都师范大学校园网为分析案例，设计开发一个Web环境下基于Web服务技术的教学资源共享系统，旨在对现在系统做尽量少改动情况下实现资源共享。此系统是一个多层的分布式应用程序，主要由3个逻辑层组成：数据层、业务对象层和用户界面层。被集成的资源库由多个分布在校园网内的子资源库的，各个子资源库拥有自己的发布和管理系统，已经具有自身的自治性，在实现集成的同时每个数据库系统仍保有自己的应用特性、完整性控制和安全性控制。系统通过一个元数据规范集来对资源描述进行标准化，此元数据集对内作为中间层与各子资源系统的交换标准，对外则作为呈现给用户的描述标准。论文第一章主要介绍了课题背景、主要研究内容和系统设计目标以及Web服务研究现状和国内外关于异构数据共享的研究现状。第二章主要介绍了Web服务技术的工作原理以及应用于教学资源共享的优势与不足。第三章主要从校园网角度分析了教学资源共享的需求和校园网环境特点，并对用户需求和系统运行流程做了初步分析。第四章介绍了几种流行的元数据规范，并结合系统自身的特点设计了系统的元数据规范。第五章为系统体系结构设计，从软件架构角度对系统结构和功能框架进行分析和结构设计。第六章重点介绍了全局资源查询的设计与实现，全局资源查询功能是系统的一个重点和技术难点。第七章介绍了全局文件资源传输代理设计与实现，以解决整个校园网内文件的传输问题。第八章为系统实现结果、总结与展望。更多还原

【Abstract】 This article mainly discusses the design of a teaching resources sharing system based on Web service technology. We had designed a teaching resources sharing system under Web environment which using Web service technology and took the capital normal university intranet as an analysis case, which is a multilayered distributional application, it composed by 3 logical levels: data level, service object level and user interface level. This resource sharing system was integrated by many sub-resources storehouse systems, these sub-resources storehouse systems are self-managed and have their own management systems, each sub-resource sharing system is a autonomy and complete system, the integration is a high level integration and need every sub-resources system to realize a standard web services interface..The first chapter introduces the topic’s background, a review about relational researches, the context of the research and the goal of this system.Second chapter mainly introduces the Web service technology’s principle as well as applies to the teaching resources sharing and its insufficiency.Third chapter mainly analyze the demand of teaching resources sharing and the characteristic of campus network environment, and has a fundamental analysis of the work flow for the system.Fourth chapter introduced several kinds of popular Metadata standards and developed our own Metadata specification based on the characteristic of capital normal university.Fifth chapter mainly discusses the structure and frame of the system, describe the system in software develop angle.Sixth chapter introduced the design and realize of file transfer function and inquiry function, which is the key functions of the system.Seventh chapter introduced the design and realize of global file transfer and the solves of file transfer in campus intranet.更多还原
