基于系统菜单项的用户权限管理实现

Implementation of User Authority Management Based on System Menu Items

用户权限管理是数据库系统最基本、最重要的功能之一.首先探讨了常用的用户权限控制方法及其特点;然后提出了一种基于菜单项的通用角色权限控制方法,并给出了数据库表的设计,菜单项遍历类的定义和实现,以及基于树形结构的角色权限设置窗口的实现.最后,结合开放式机房管理系统,介绍了这种方法在系统中的应用.

The management of user authority is one of the basic and important functions of a system. Firstly, the frequently used methods of control user authorities and their characteristics are explored. Secondly, a general user authority management method based on menu items is proposed, and then the design of the ta- bles, the design and implementation of the menu item traversal class, and the design and implementation of a window using a tree - view to set role permissions are given. Finally, the application of this method in an open computer- room management system is introduced.
