这节我们说下权限系统的特点,本系统采用的是MVC4+EF5+IOC 接口编程的架构,其中的权限树用的是DWTree,功能上做到灵活，授权操控细致，权限可以细到按钮级别
，为了部署简单,导致设计和编码上也是比较复杂
该系统主要功能如下：
- 自定义操作动作(如增加、删除、修改、审核等，不再是以前见过的那种粗粒度的 按模块分配权限，或者稍微先进点的规定死某几个操作了)。
- 无限级功能模块管理，自定义模块排序，可以更好地对整个系统中所有模块进行 分类管理。
- 灵活地为各模块分配操作，即每个模块有哪些操作需要被控制(将步骤1中添加的 操作按需分配给各模块)。
- 对所有用户基础信息进行管理，实行有效期机制，过期自动失效，在有效期间亦 可强制停止用户使用。
- 自定义角色，可以起个听起来通俗易懂的名字。
- 任意角色可任意组合系统权限功能点(比如某个模块里他只能修改数据而不能添加 或删除等其它操作)
- 一个用户可有多个角色(多身份)，一个角色也可以被多个用户拥有(同身份)（多对多），灵活授权。
- 按角色给用户授权，当授权对象数量庞大的时候就可大显身手了(比如给公司全体 员工授权)。
- 按用户分配角色，当某个用户以多种身份出现在系统中的时候，希望分配多个角 色。
- 菜单的显示根据权限来显示，如果一个用户拥有模块的一个以上操作码权限，则菜单被显示，否则不读取
从数据库结构来看，一共设计了七个表(table)，表名及功能分别如下：
1.模块管理（SysModule）
系统菜单的管理,支持无限级别树,表我们在之前的文章已经建好了
2.用户表（SysUser）
系统会员,登录系统的唯一凭证
3.角色组（SysRole）
对角色组基本信息进行管理。用户可以自定义成各种各样的角色组，然后对用户授权
4.模块操作码（SysModuleOperate）
操作码表的父表是模块表，一下模块下面有多个操作码，比如增加，删除，审核，修改等.
5.授权表（SysRoleSysUser）
用户和角色组的对应表，一个角色拥有多个用户，一个用户可以拥有多个角色
6.角色权限表(SysRight)
将角色与系统中的权限点关联起来，也就是完成授权的动作。
7.被付权限操作码表(SysRightOperate)
保存有权限的角色的操作码，当有一个操作码被赋予权限时，将激活对应的菜单
我们通过一张物理模型图看出表与表之前的关系
现在通过物理模型转化为SQL语句

复制SQL语句放到查询窗口执行一下然后用视图看看他们之间的对应关系
今天就到这里了
