A.易分析性

B.易理解性

C.易学性

D.易操作性

答案

参考答案:A

解析:

《软件工程产品质量》(GB/T 16260.1—2006)中定义了内部和外部质量的质量模型。它将软件质量划分为6个特性(功能性、可靠性、易用性、效率、维护性、可移植性),并进一步细分为若干个子特性。这些子特性可用内部或外部度量来测量。软件质量特性包括:

①功能性:与一组功能及其指定的性质有关的一组属性这里的功能是指满足明确或隐含的需求的那些功能。

②可靠性:与在规定的一段时间和条件下软件维持其性能水平的能力有关的一组属性。

③易用性:与一组规定或潜在的用户为使用软件所需作的努力和对这样的使用所作的评价有关的一组属性。

④效率:与在规定的条件下软件的性能水平与所使用资源量之间关系有关的一组属性。

⑤维护性:与进行指定的修改所需的努力有关的一组属性。

⑥可移植性:与软件可从某一环境转移到另一环境的能力有关的一组属性。子特性的内容见下图。

可见易分析性属于维护性,易理解性、易学性、易操作性属于易用性。
