Modular decomposability
A software construction method satisfies Modular Decomposability if it helps in the task of decomposing a software problem into a small number of less complex subproblems, connected by a simple structure, and independent enough to allow further work to proceed separately on each of them 如果一个软件构造方法能把一个软件问题分解成很多较简单的子问题,并把这些子问题用一个简单的架构连接起来,而且能够完全独立的在每一个子问题上再更进一步的分解,那么,这个方法就满足模块的分解性.
