摘    要
随着Internet/Intranet技术的发展，基于WEB的应用日益广泛，企业通过Internet/Intranet可以实现信息的快速收集、发布、存储、处理和交流，而随着企业信息化，集成化程度，应用程序互操作程度越来越高，现在比较流行的WEB应用程序开发平台都无法满足企业的发展要求。
本文对当前WEB应用程序开发平台中面对企业集成化出现的问题进行深入的研究，并结合XML技术，利用其规范性、自描述性、数据表达的灵活性等特点提出了针对此问题的解决方案－基于XML技术和.NET平台的科技工作管理平台，它对传统三层WEB应用结构进行改进，在层与层之间广泛地使用XML技术构造新的三层体系。本文详细介绍XML技术的原理和在该WEB开发平台中的应用，利用XML的原理和特点如何解决出现的数据共享、跨平台应用、可扩展性，服务器性能改善等问题。根据系统分析设计的要求，本文分为四个部分：第一部分是问题的分析和提出，主要是关于科技平台之类的WEB应用平台所面临的挑战；第二部分是XML基础知识，规范，体系结构，应用构架以及.NET平台中XML的应用。第三部分是科技工作管理平台的设计，主要是采用比较适合的解决问题的方法设计出该科技工作管理平台，并结合问题对当前软件理论发展的热点之一的WEBSERVICES技术和软件复用技术进行了研究。第四部分则是科技工作管理平台的实现，我们结合具体的项目对上述解决方法和理论研究的成果进行了验证。

Abstract
With the development of the technology of Internet and Intranet, the application, which based on Web, has been widely used in all kinds of fields. Enterprises could quickly realize information collection, issuance, storage, management and communication. However, as the level of companies’ informatization, integration and application’s interoperability becomes more and more higher than before, the popular develop platforms of Web application programmes have been not met with the companies’ need of development at present time.
This paper introduces a deep research about the questions emerged from the process of enterprises’ integration with develop platform based on Web nowadays. It also brings up the technology of XML, which has some specialty, such as normative, self-descriptiveness, flexibility of data description and so on. We apply XML in the Web develop platform to answer the questions and put up a platform which is named scientific and technological work management platform based on XML and .NET. It improves the traditional three layer based on Web application, the traditional was replaced by a new construction by widely using XML between layers in it. In this paper, we concretely introduce the principle of technology of XML and how to deal with the problems in traditional platform through the XML, such as data share, the application which crosses the platform, extensibility and improvement of Server capability. The paper is divided into four parts at the principle of need of system analysis and design, the first part presents that problems brought up by the users and how to deal with the problems, most of them challenge the development of the scientific and technological work management platform based on Web, the second part is composed with the primary knowledge of XML, which includes criterion of XML, construction and application system of XML, it also covers the application of .NET which has intensive relationship with XML, the third is the design of the scientific and technological work management platform based on Web，namely, the methods that how to find proper ways to build the platform and do the research about the theory of Web Services and software reuse which is the focus in current computer science research, the last part is about the realization of the system, we prove the results of our research work by the examples.
