基于UML和构件技术的政务管理系统的实现-计算机技术专业论文.docx

摘要 摘 要 UML 是一种可视化的建模语言。构件技术一般指基于构件的软件开发技术 (简称 CBSD)，它是一种新的软件工程方法，力求模仿工业化大生产的模式，提 高软件生产力。 本文研究的是在基于构件的软件开发中，将 UML 建模贯穿整个过程。利用 UML 图的良好沟通特性，促进用户、分析人员、设计人员、编码和测试人员对所 开发系统的统一认识。遵循构件化的开发思想，在分析时就要考虑 便于构件开 发。设计时就应利用构件的复用性，看是否存在可复用的构件，如需要开发才 进行自开发构件的设计。在系统实现的时候包括构件实现 (编码)和构件组合， 最后根据部署图进行系统的部署。通过 CBSD 和 UML 的结合使得在系统开发能提 高效率、降低成本、缩短工期和保证质量。 本文根据在电子政务公文管理系统项目中 UML 和构件技术结合应用及当前 构件化开发的状况提出符合学校需要的一种基于构件和 UML 的系统开发方案。 该方案是公文管理系统项目实践的结果，能够提高开发效率。公文管理系统已 实际应用于用户，实现了设计目标，用户感到比以前的系统更适合业务的处理， 性能也有很大的提高并运行良好。 【关键词】：UML；构件；公文管理系统 Abstract Abstract UML is a kind of visual modeling language. Component technology point the technology of software development (abbreviated as CBSD) based on component the same, it is a new soft project method, make every effort to imitate the mode of the industrialized great production, improve software productivity. Unite the description of the component in the course developed in the component with UML, could achieve the purpose that puts in an position to the greatest extent of the component, thus could be suitable for the changeable software system. UML, and component. technology,etc. analyze, design respect different combination of technology.marin trend of software development. What this text studied is in the software development based on component, the whole course of running through UML modeling. Utilize linking up the characteristic well of UML picture, promote users, analyze the personnel, designer, code and tester to the systematic unified understanding developed. Follow the component development thought, will consider benefiting component development while analyzing soon. Should utilize the replying the spending of the component at the time of the design, the component that can be replied and used exists to see, if go on developing the design of the component if developing. Including the component is realized (code) and component association when the system is realized, according to disposing and pursuing to carry on systematic arrangement finally
