向各位大神求教关于数据库设计方面的问题
本人菜鸟一枚，最近在开发一个基于php+mysql的报修系统，开发到一半发现数据库的结构有个严重的错误。如图
主要问题出现在user表和web_order表的关联上，user表的主键uid作为web_order表的外键进行关联，重点在web_order表的w_workid的值也是user表的uid字段的值，原因在与我的用户表的用户权限只用了一个power字段区分，这个系统有普通用户，维修员，秘书，管理员4个权限，系统逻辑上需要标示维修单是谁报修的（用户），是谁维修的（维修员），是谁分配的（秘书），这让我不知改如何进行关联，改如何修改表结构，求各位大大帮忙，感激不尽。
------解决方案--------------------
报修时 web_order表 会有一条记录
维修时 web_order表 会有一条记录
分配时 web_order表 同样会有一条记录
怎么会关联不上呢？
------解决方案--------------------
既然秘书分配和维修员接单是通过update表的state字段表示，并不会增加记录
那么你也就没有地方记录是谁在操作
于是自然也就无法分辨出是谁在进行了什么操作
对于这么浅显的问题，你都不能找出解决方案吗？
------解决方案--------------------
加一个操作日志表，记录人员 时间 什么操作等等信息
