The importance of layering in software development
The importance of the framework is that it implements part of the functions,
and can well

In order to realize the " high cohesion and low coupling " in software engineering .
Dividing the problems into individual solutions is easy to control, easy to extend, and easy to allocate resources.
Our common MVC software design idea is a good layered idea.
