| 摘 要： | 针对传统RBAC模型的角色管理过于复杂，权限粒度不够细化等不足，提出了一种改进模型，并详细描述了该改进模型的特点，引入了限制元素和特有权限等新概念。通过将功能模块及其相关操作映射为权限数据，使得权限代码和业务逻辑代码完全解耦。 最后结合实例，详细阐述了该改进模型应用于权限管理系统的实现过程，以及该模型的优缺点。

| Abstract: | An improved model was proposed for the deficiencies of traditional RBAC model in role-management such as over complexity and rough granularity. The characteristics of this model were described in detail, in which permission constraint elements and special permissions were introduced. Acting as permission data, other functional modules and their related operations can make the couple of the permission codes and operation logics eliminated. As a conclusion, implementation of this improved model in system of permission management was described in detail, also including its advantages and disadvantages. |
