For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the(71) of a software-intensive system. As the(72) standard modeling language, the UML facilitates communication and reduces confusion among project(73) . The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to(74) everything from enterprise information systems and distributed Web-based applications to real-time embedded systems.
The UML is not limited to modeling software. In fact, it is expressive enough to model(75) systems, such as workflow in the legal system, the structure and behavior. of a patient healthcare system, software engineering in aircraft combat systems, and the design of hardware.
To understand the UML, you need to form. a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML.
A．classes
B．components

A．Programming
B．Analyzing
C．Designing
D．Modeling
正确答案：D
解析：UML的核心关注内容是建模，而建模是一个开放性的问题。建模是采用合适并预先定义的符号来描述捕获的思想、关系、决策和需求，并且建模可应用到多个领域。建模对不同的人有不同的含义，可以使用UML中不同的部分来描述你所要涵盖的内容。一般来说，UML模型是由一个或者多个diagram组成。一个diagram使用图形化的方式描述了事物以及事物之间的关系，而事物代表了真实世界中的对象、软件构件或对象行为。常常一个独立的事物会在多个diagram中展现，每个diagram建模了该事物的不同方面。UML 2.0将diagram分为两大类：结构化diagram和行为diagram。结构化diagram主要用于捕获系统的物理组织结构，如一个对象与其他对象的关系。行为diagram则用于捕获需求、操作以及元素内部状态的变化。 -
