    A.对系统的原型化实例建模和对传递的消息建模

    B.对系统的消息建模和对数据建模

    C.对系统的语境建模和对系统的需求建模

    D.对系统的语境建模和对数据建模


    正确答案:C
    解析:用例图用于对系统的静态用例视图进行建模。这个视图主要支持系统的行为,即该系统在它的周边环境的语境中所提供的外部可见服务。当对系统的静态用例视图建模时,可以用下列两种方式来使用用例图。(1)对系统的语境建模对一个系统的语境进行建模包括围绕整个系统画一条线,并声明有哪些参与者位于系统之外并与系统进行交互。在这里,用例图说明了参与者及其所扮演的角色的含义。(2)对系统的需求建模对一个系统的需求进行建模,包括说明这个系统应该做什么(从系统外部的一个视点出发),而不考虑系统应该怎样做。在这里,用例图说明了系统想要的行为,通过这种方式,用例图使我们能够把整个系统看作一个黑盒子。你可以观察到系统外部有什么,系统怎样与那些外部事物相互作用,但却看不到系统内部是如何工作的。

    近十年来,统一建模语言(UML)已经成为工业标准,它可用宋可视化、规范化说明、构建以及文档化软件密集系统中的开发制品。作为事实上的工业标准,UML能够方便项目相关人员的沟通并减少理解上的二义问题。UML 2.0标准扩宽了该语言的应用范围,它所具有的表达能力能够让用户对企业信息系统、分布式Web系统和嵌入式实时系统进行建模。UML不仅能够对软件系统进行建模,实际上,它具有足够的能力去对法律系统中的工作流、病人监护系统中的结构和行为、飞行战斗系统和硬件系统进行建模。为了理解UML,需要具备该语言的概念模型,这需要学习三个主要元素:UML的基本构造块,基本构造块的关系规则和应用这些构造块与规则的通用机制。
