design pattern
In software engineering, a design pattern is a general reusable solution to a
commonly occurring problem within a given context in software design.

设计模式就三个准则：1）中意于组合而不是继承，2）依赖于接口而不是实现，3）高内聚，低耦合。你看，这完全就是Unix的设计准则。

Design Patterns are best practices how to solve common know problems.

面向对象编程注重的是：1）数据和其行为的打包封装，2）程序的接口和实现的解耦。
OOP的本质就是——对数据和与之关联的行为进行编程。即便就算是这样也不完全对，因为：
Sometimes data is just data and functions are just functions.
