问题 单项选择题

以下关于体系结构风格和体系结构模式的描述中,错误的是______。

A.与体系结构模式一样,体系结构风格也对体系结构设计施加一种变换
B.相对于体系结构风格,模式涉及的范围要大一些,它更关注体系结构的整体
C.体系结构模式在体系结构上施加规则,描述了软件是如何在基础设施层次上处理某些功能性方面的问题
D.体系结构模式倾向于在系统结构的环境中处理特定的行为问题

答案

参考答案:B

解析: 一种体系结构风格就是一种施加在整个系统设计上的变换。其目的是为系统的所有构件建立一个结构。
与体系结构风格一样,体系结构模式也对体系结构设计施加一种变换。然而,两者在许多基本方面存在不同:①体系结构模式涉及的范围要小一些,它更多集中在体系结构的某一局部而不是体系结构的整体;②体系结构模式在体系结构上施加规则,描述了软件是如何在基础设施层次上处理某些功能性方面的问题;③体系结构模式倾向于在系统结构的环境中处理特定的行为问题。
