Research and Design on Budget MIS Access Control Policy
预算管理信息系统访问控制策略的研究与设计

The new representations of roles and permissions are discussed.An access control policy of budget MIS is also presented.This access control policy divides permissions into function-module permissions and data permissions,and divides roles into system roles and user-defined roles.Associating function-module permissions to system roles and data permissions to user-defined roles,the policy simplified implementation of access control framework,and enhanced the efficiency of proces-sing.
