摘要
为了增强学院办公管理系统的安全性,采用了基于角色的访问控制技术。在系统中分两步来定义角色,第一步定义各角色类,将各类用户在系统中的共同性抽象为功能项,并设置"用户/角色类/模块功能项"的关系。第二步定义角色子类,在模块功能项的实现中,根据工作内容、用户的职权以及学院办公管理的工作职责等确定用户所拥有的角色类对教师和学生相关数据的操作权限。
In order to enhance the security of school office management system,the role-based access control technology has been used. There are two steps to define the role.The first is to define "role class".Abstract the common features of different users in the system as function of the abstract.Set the relationship of "user/role class/function modules".The second is to define "role sub-class".In the realization of the function modules,determine the permissions of user's role class operating the data about teachers and students according to work,user's authority and duty of school office management.
