功能模块独立性是由内聚性和耦合性两个定性指标来度量的。内聚性是度量一个功能模块内功能强度的一个相对指标。耦合性则用来度量功能模块之间的相互联系的程度。
内聚
内聚是从功能角度来度量功能模块内的联系,一个好的内聚功能模块应当恰好做一件事。它描述的是功能模块内的功能联系。
内聚有如下的种类,其内聚度由弱到强排列:
☆偶然内聚。一功能模块中的代码无法定义其不同功能的调用。但它使该功能模块能执行不同的功能,这种功能模块称为巧合强度功能模块。
☆逻辑内聚。这种功能模块把几种相关的功能组合在一起,每次被调用时,有传送给功能模块参数来确定该功能模块应完成那一种功能。
☆时间内聚。这种功能模块顺序完成一类相关功能,比如初始化功能模块,它顺序为变量置初值。
☆过程内聚。如果一个功能模块内的处理元素是相关的,必须以特定次序执行则称为过程内聚。
☆通信内聚。这种功能模块除了具有过程内聚的特点外,还有一种关系,则它的所有功能都通过使用公共数据而发生关系。
☆顺序内聚。如果一个功能模块内的处理元素和同一个功能密切相关,这些处理必须顺序执行,通常一个处理元素的输出数据作为下一个处理元素的输入数据,则称为顺序内聚。
☆功能内聚。如果一个功能模块包括并仅包括未完成某一具体任务所必需的所有成分,或者说功能模块中所有成分结合起来是为了完成一个具体的任务,此功能模块称为功能强度模块。
