推荐答案

请参阅 http://en.wikipedia.org /wiki/Multitier_architecture [^ ].

作为起点:
1.确定代码中的图层.
2.重新排列，使一层仅取决于下一层.

See http://en.wikipedia.org/wiki/Multitier_architecture[^].

As a starting point:
1. Identify what your layers are in your code.
2. Re-arrange such that one layer depends on the next layer only.
