摘要
在分析RBAC授权模型原理的基础上,提出了用户-权限组-权限的授权管理模型,并利用PowerDesigner进行了数据模型（CDM和PDM）的设计,最后详细阐述了基于VB和SQL Server的材料信息系统中用户授权管理的实现。该授权管理模型的设计与实现具有很强的通用性。
The user-permission group-permission model on administration of authorization, based on RBAC model, is presented in this paper. Then the data models (CDM & PDM), designed with data architect in power designer, are introduced. Lastly the realization for the models in MIS of material exploited by VB and SQL server is described in detail. The fact shows that the design and realization are universal.
