通用的RBAC权限系统

本文只介绍权限系统的设计,暂不涉及PowerDesigner工具的使用,网上有很多这里不再多做介绍.
           

1. 简单的介绍下RBAC

    基于角色的权限访问控制（Role-Based Access Control）作为传统访问控制（自主访问，强制访问）的有前景的代替受到广泛的关注。在RBAC中，权限与角色相关联，用户通过成为适当角色的成员而得到这些角色的权限。这就极大地简化了权限的管理。

  a. 最简单的RBAC五张表

表名	建表名称	描述
人员表	s_user_t	存储系统人员信息
角色表	s_role_t	存储系统角色信息
资源表	s_resource_t	存储系统资源信息
人员角色关系表	s_userrole_t	存储系统人员和角色之间的关系
角色资源关系表	s_roleresource_t	存储系统角色和系统资源的关系

  b. 如果你还想要更多

    仔细观察一下上面的图片也许你就明白为什么叫基于角色的权限访问控制了,因为把用户和权限关联起来的唯一基础表就是角色表,角色表通过关系表分别与人员表和资源表进行了关联.如果你有了这5张表基本可以满足一个不太复杂的权限系统了,可以用一句话表示:麻雀虽小五脏俱全.

    当然如果你有更复杂的需求,也可以以此为基础继续扩展,如:

     1, 需要组织机构,系统需要展现出用户的组织关系,可以在人员表旁边新建一个组织结构表和组织结构人员关系维护表.如果你要做的权限系统非常庞大.

     2,市下有多个区县,总公司下有多个分公司,分公司下还有多个群组,可以在角色上面继续加建:用户组,区县组,分公司组等,总之万变不离之宗,有这五张表为基础就可包罗万象满足一般系统的绝大部分需求.

2. 建表语句(本例使用数据库为oracle)
