基于UML的面向对象建模方法的研究

为了研究较好的软件建模方法,运用UML中的5种图对面向对象建模的方法进行讨论及技术研究,提出如下建模过程：首先是系统需求;随后分析问题领域,建立系统的用例图;接着,建立系统的静态结构模型,并将系统的功能需求分解到各个对象类,以确定各个对象类的责任;然后,建立系统的动态行为模型;最后,给出物理模型。通过实例,对UML的面向对象建模机制做了系统概述,表明UML是一种优秀的建模语言,使用UML有助于开发者对整个系统有清晰的认识,从而建立各种系统模型,为后期编码工作做好充分的前期准备。

Research on Method of Object-oriented Modeling Based on UML

In order to study a better method of software modeling, the five diagrams in UML is adopted to achieve the object-oriented modeling methods. The following modeling steps are proposed： analyze the areas of the problem, establish the use case diagram of the system; set up the static structure model of the system, decompose the system＇s functional requirements to each object class, determine the responsibility of each object class; and then establish the dynamic behavior model of decency and physical model. The object-oriented modeling mechanism of UML is summerized systematically through exampies. It shows that UML is an excellent modeling language. UML will help the developers to have a clear understanding to the whole system, thus establish the system model and make the prophase preparation for later coding.
