基于RBAC的工作流管理在UBIS系统中的应用

Workflow Management Based on RBAC in Application on Unified Business Information Service System

文章针对工作流管理系统及基于角色访问控制的特点和实际应用的需求,在将基于角色的访问控制与工作流管理系统相结合时引入了约束的概念,从而简化权限控制的复杂度,提高了系统的安全性和性能。同时,文中使用了UML对系统的体系结构进行了详细分析介绍。最后,通过模型在中国联通统一经营信息服务系统中的实际应用,展现了基于RBAC的工作流管理系统在办公自动化系统中的优越性。

Taking the characteristics of workflow management system and RBAC （Role-Based Access Control） and the requirement of practical application into consideration,the paper presents a workflow management model based on RBAC which includes the concept of constraint. So the new model can reduce the complexity of the permission management and increase the security and performance of the system.This paper applies the UML into introducing the system architecture in detail.Finally,through the practical application in China Unicom＇s Unified Business Information Service system,it shows the superiority of the workflow management system based on RBAC in office automated system.
