YY面试，对MVC框架M层的理解，求指导
根据我的理解，平时用来处理数据的方法，我把它封装成类，以后遇到同样的数据处理我就调用这个类，这个类属于M层，处理数据。
面试官问我：
我们抓取网页有这么几步
1.根据URL抓取网页
2.正则表达式处理html元素
3.将抓取到的内容存入数据库
以上这三部哪一步处于M层？
我觉得三步都属于啊。
求大家指导我的理解是否有错，错在哪里，拜托了~
如果上面三步哪一步不是M层，那它属于MVC的哪一层？？
回复讨论(解决方案)
个人觉得第3部属于m层.
因为第3部进行了数据库的查询.
第一步是不是有可能属于C层？这个要看项目的定义了。
3必然是 12可算可不算吧 我理解
首先3是对数据库的直接操作，肯定是一个通用性非常强的底层接口
2也可以算M，针对XX网站做的处理，来源于该网站的html都可以调用
1照样可以是M，无非是在2的基础上增加了一个curl抓取，url作参数而已
我觉得1.2属于业务逻辑层，3是数据层
明显3，对数据的操作
1 是控制层 3是处理数据层 我是这么理解
只有3是，1,2是控制层
第三步，m是数据处理层，当然你应用逻辑也可以写在m层，只不过很不规范。
正确的mvc架构应该让c层尽可能少的处理数据逻辑，而让m来处理，否则mvc的最大优点－－代码模块化的优势就体现不出来了。
仅供参考！
MVC架构根本就没有准确定义，面试官水平不够或者故弄玄虚吧。
V是用户视角
C是业务视角
M是功能视角
三者本来就是一起合作完成任何一个功能的。抓取网页的话，对资源的请求一般写在M里。
正则表达式分析HTML这个，C和M都说得过去。在M里写好方法，C里调用是个比较好的结构。
数据库操作肯定是M，因为很多框架里，M就剩下访问数据库了。
