摘    要
隨著Internet/Intranet技術的發展，基于WEB的應用日益廣泛，企業通過Internet/Intranet可以實現信息的快速收集、發布、存儲、處理和交流，而隨著企業信息化，集成化程度，應用程序互操作程度越來越高，現在比較流行的WEB應用程序開發平臺都無法滿足企業的發展要求。
本文對當前WEB應用程序開發平臺中面對企業集成化出現的問題進行深入的研究，并結合XML技術，利用其規范性、自描述性、數據表達的靈活性等特點提出了針對此問題的解決方案－基于XML技術和.NET平臺的科技工作管理平臺，它對傳統三層WEB應用結構進行改進，在層與層之間廣泛地使用XML技術構造新的三層體系。本文詳細介紹XML技術的原理和在該WEB開發平臺中的應用，利用XML的原理和特點如何解決出現的數據共享、跨平臺應用、可擴展性，服務器性能改善等問題。根據系統分析設計的要求，本文分為四個部分：第一部分是問題的分析和提出，主要是關于科技平臺之類的WEB應用平臺所面臨的挑戰；第二部分是XML基礎知識，規范，體系結構，應用構架以及.NET平臺中XML的應用。第三部分是科技工作管理平臺的設計，主要是采用比較適合的解決問題的方法設計出該科技工作管理平臺，并結合問題對當前軟件理論發展的熱點之一的WEBSERVICES技術和軟件復用技術進行了研究。第四部分則是科技工作管理平臺的實現，我們結合具體的項目對上述解決方法和理論研究的成果進行了驗證。

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.
