针对管理信息系统，本文提出了一个实施基于角色的存取控制方法。在介绍基于角色存取控制的基础上以上海站管理信息系统为例列出实施此存取控制的步骤，包括基本表格的建立和控制函数的定义、模块流程图及各个模块的功能和相互关系。

The authors propose a detailed role based access control scheme for the general Information Management System. On the basis of brief introduction about role, the authors give each step to realize role based access control in the example system, including how many tables need to be built at first and then how to define all the control functions. At the same time,this paper gives a general module diagram of this access control scheme and analyzes these modules in detail.
