+#### 为什么 MySQL 需要编写两份代码
+
+看起来这是不必要的重复，但其实不然。`User.extend()` 定义的是用户表中各列的**默认值**，而 `Database.extend()` 定义的是数据库的**字段类型**，会被用于自动建表和补全字段。换句话说，如果你已经手动建好表了，那么你确实不需要编写后面的额外代码。但是反过来，如果你是插件开发者，你的用户很可能不知道这个插件需要哪些用户字段，因此这样的写法可以在用户安装插件的时候就自动创建字段。

 ## 扩展数据库
 
 由于 Koishi 的数据库实现使用了注入策略，因此无论是字段，表，方法还是数据库都是可以扩展的。
