RBAC在学生成绩管理系统中的实现

为建立更加安全高效的访问控制系统,介绍了基于角色的访问控制（RBAC）在学生成绩管理系统中的实现。首先论述了基于角色访问控制的基本思想和核心模型,并结合学生成绩管理系统,根据系统中用户的职责对用户进行角色定义,同时明确各角色的不同权限。然后,根据RBAC的基本思想,分别给出学生成绩管理系统中用户表、角色表、角色权限表和菜单资源表以及它们之间的映射关系,建立学生成绩管理系统的访问控制数据库,最后使用VC＋＋编程实现了RBAC在学生成绩管理系统中的应用。实际应用结果表明,在信息量大、用户多、权限分配复杂的管理系统中,RBAC是一种方便、安全、高效的访问控制机制。

Implementation of Role-Based Access Control in Student Achievement Management System

To establish a more secure and efficient acess control system,this paper introduces the implementation of role-based access control in student achievement management system. First discusses the basic ideas and model of RBAC,as well as applys it to student achievement management system,according to the responsibilities of users in this system to define the roles of users and define different permissions of different roles. Then according to the basic idea of RBAC,it gives user table,role table,role permission table and menu resource table of student achievement management system,to creat access control database of student achievement management system. Finally use VC＋＋ programming to accomplish RBAC in student achievement management system. Practical results show that,in this system which has lots of information,users and complex permissions,Role-Based Access Control（RBAC） is a kind of access control mechanism which is convenient,secure and of high-performance.
