PDM权限管理模块设计与开发

Design and Realization of Permission Management Model on PDM

提出了面向服务的架构(Service-Oriented Architecture,SOA)和基于角色的访问控制技术(Role Based Access Control,RBAC)相结合的权限管理模型,为系统提供统一的授权管理和访问控制服务,提高了系统的信息安全。并以该模型在PDM系统的实际应用阐述了权限管理模块的设计方法,实现了开放、动态环境下的权限管理。

The permission management model has been developed with service-oriented architecture（SOA） and Role Based Access Control（RBAC） which offers a universal service for permission and access control to enhance information security of system.This paper explains the detailed method to design the permission management model of the PDM system and realizes the permission management in open and dynamic enviroment.
