可重用性:解决方案的大多数部件是可重用的。
另外还需要一套丰富的可用部件;不过,可以重用一个已有的数据采集器或文件浏览器组件,而不必自己编写它们。
You also want a rich set of available widgets; you're usually better off reusing an existing date picker or file browser component, for example, than writing your own.
也就是说软件应该由可重用的部件构造而成。
The idea is that software should be developed such that it can be constructed from re-usable parts.
