DBU-400模塊獨(dú)立性

功能模塊獨(dú)立的概念是功能模塊化、抽象、信息隱蔽和局部化概念的直接結(jié)果。

抽象是指對(duì)事物、狀態(tài)或過程之間所存在的某些相似的方面集中和概括起來，而暫時(shí)忽略他們之間的差異，即考慮抽象事物的本質(zhì)特征而暫時(shí)不考慮他們的細(xì)節(jié)。信息隱蔽是指再設(shè)計(jì)功能模塊時(shí)使得一個(gè)功能模塊內(nèi)所包含的信息（過程或數(shù)據(jù)），對(duì)于不需要這些信息的功能模塊來說是不能訪問的。信息隱蔽原則對(duì)于以后在軟件維護(hù)期間修改軟件時(shí)會(huì)帶來·大的好處，因?yàn)榇罅繑?shù)據(jù)和過程是軟件的其他部分所不能覺察的，因而再對(duì)某個(gè)功能模塊修改時(shí)就不大會(huì)影響到軟件的其他部分，所謂局部化是指把一些關(guān)系密切的軟件元素在物理位置上彼此靠近。

功能模塊獨(dú)立性是通過制定具有單一功能并且和其他功能模塊沒有過多聯(lián)系的功能模塊來實(shí)現(xiàn)的。每個(gè)功能模塊只涉及該軟件要求的一個(gè)具體子功能，而且與軟件結(jié)構(gòu)的其他部分的接口是簡(jiǎn)單的。

功能模塊獨(dú)立性好的軟件接口簡(jiǎn)單，易于編制，獨(dú)立的功能模塊也比較容易測(cè)試和維護(hù)，限制了功能模塊之間由于聯(lián)系緊密而引起的修改副作用。獨(dú)立性是保證軟件質(zhì)量的重要因素。
