一、读前思考问题
1.1、什么是建模
1.2、建模不建模，代码写出来有什么不一样吗？
二、思考
2.1、问题一
2.1.1、百度百科定义
建模，就是建立模型，就是为了理解事物而对事物做出的一种 抽象 ，是对事物的一种无 歧义 的书面描述。建立 系统模型 的过程，又称模型化。建模是研究系统的重要手段和前提。凡是用模型描述系统的 因果关系 或相互关系的过程都属于建模
2.1.2、统一语言
模型是对真实世界的抽象，明确定义了各种元素、以及元素之间的关系，可以用来做逻辑推导--《模型思考者》
互联网环境下，往往在基于理论的基础上会进行裁剪(比如时间、资源、成本、用户等等因素)
分析过程：建模的本质是对于事物的抽象，方便我们理解和分析事物的本质。
2.1.3、问题答案
统一答案：建模的本质是对于事物的抽象过程，方便我们理解和分析事物的本质
行业答案：建模的本质是基于当前事物域问题，通过实际经验，进行事物本质(元素和元素之间关系)持续探索的过程。
2.1.4、案例
2.1.4.1、未建模前
2.1.4.2、建模以后
2.2、问题二
2.2.1、问题答案
正确答案和理论、实际代码会有体现上不一样，但是不是绝对的（实际上取决于研发控制）。
对于研发知识的掌握和规范要求比较高，否则很容易只是形式主义。

}不知道看到这里的读者你是否发现建模的意义了呢？
