【摘要】 UML（Unified Modeling Language）是Rational Software公司和她的合作伙伴共同制定的用于描述、可视化和构架软件系统以及商业建模的语言，它涵盖了面向对象的分析、设计和实现，融合了早期面向对象建模方法和各种建模语言的优点，为面向对象系统的开发、软件自动化工具与环境提供了丰富的、严谨的、扩充性强的表达方式。UML代表了在大型、复杂系统的建模领域得到认可的“优秀的软件工程方法”。 UML的应用是以系统的开发流程为背景，但UML只是标准的建模语言，而不是一个标准的开发流程。不同的组织、不同的应用领域需要不同的开发过程。软件系统的开发流程中，需求分析是其中决定性的一步，本文的主旨就在于探讨UML如何应用于软件需求分析阶段并在此基础上建立了一套模型。 最后，本文以“基于Web的远程教学系统应用平台”的开发为例，展示了所建模型的具体运用。更多还原

【Abstract】 The Unified Modeling Language (UML), which is designed by Rational Software Corporation and its partners , provides system architects working on object analysis and design with one consistent language for specifying, visualizing, constructing and documenting the artifacts of software systems. UML is the convergence of best practices in the object-technology industry. And it is a rich, precise, extensible modeling language for object-oriented system development and software developing automation environments. UML is the representation of excellent software engineering methodology which is approbated in large-scale and complex modeling field. Although system development flow is the background of UML applciation, UML is only a standard modeling language and not a standard development flow. Different organizations and different application field has different development process. During the course of software developing, requirement analysis is a decisive step. The lemma of this article is to discuss UML application on requirement analysis and construct a model based on it. Finally, this thesis uses DEVELOPMENT OF REMOTE EDUCATION SYSTEM OF CHINA AGRICULTURAL UNIVERSITY as a example to explain how to use this model.更多还原
