基于UML 基于UML 1j RUP的软件薄工程的研究与应用 摘 要 随着信息化步伐的加快，软件危机呈现出愈演愈烈的趋势，如何有效维护现 存软件以缓解危机的研究也变得更加紧迫。软件再工程通过利用重新抽象出设计 模型、将新的技术和需求应用到现存系统，从根本上提高系统的性能和可维护性， 正日益受到重视。 本文正是在这～背景下，以软件再工程为主题，对其有关技术和方法进行了 深入的研究。 文章介绍了UML和RUP这两项关键技术，UML与RUP是软件工程中的新技术， 本文所探讨的软件再工程模型是基于这两项技术提出的。 本文在研究软件再工程传统模型的基础上，吸收UML和RUP的思想，构建出 基于UblL和RUP的软件再工程的迭代、增量模型，并定义其阶段和关键活动。此 再工程模型对充分挖掘现存系统的信息，将这些信息运用到目标系统中有着重大 意义。对软件再工程迭代、增量模型的各关键活动的任务和分析方法本文都进行 了详细阐述，描述了此模型是如何分析现存系统，创建目标系统的各个细节和整 个过程。 本文以本人参与的江西省电力公司医疗保险缴费报销系统的项目为应用实 例，将再工程的迭代、增量模型运用于实践中，提出了总体的再工程方案。 关键词：UML，RUP，软件再工程 基于UML与RUP的软件雌工程的t叶宄与应用ABSTRACT 基于UML与RUP的软件雌工程的t叶宄与应用 ABSTRACT With the faa development of information technology．software crisis become even more serious．For the purpose of mitigating the crisis，researched how to maintenance the existing system more effectively is badly needed．Software reengineering is being attached much more importance in recent years，for it’s dramatic enhancing performance and maintainability of the existing system by re—abstract design model and incorporating new technologies to the existing system． TMs paper discusses software reengineering．further researches related techniques and methods． The paper presents two key technologies，UML and RUP．The software reengineering model which the paper discusses is based on this to technologies． Based researching the traditional software reengt’neering model，consult the cores of UML and RUP，design the iterative and increasing software reengineering model based on the UML and RUP．and define the phases and important actions．The reengineering model has important meaning to sufficiently understand the information ofthe old system and apply the information to new system．The paper expatiates each important actions of the iterative and increasing software reengineering model， describes each detail and the whole process about the model how to analyze the old system and establish the new system． The paper combines the iterative and increasing model of reengineering to the practice，outlines
