基于角色控制的分布式 PDM系统(英文)

Distributed PDM Systems Based on Role Access Control

提出了一种适合于工程设计中基于协同工作的多用户的分布式 PDM系统的软件结构 .介绍了一个相关的软件模型 ,这个软件模型说明了如何通过添加 CSCW和 RBAC机制来扩展现存的 PDM系统 .在讨论了 PDM、CSCW和 RBAC的基础上 。

The objective of the work presented in this paper is to provide a software architecture for distributed PDM environments especially suited for multi user based cooperation in engineering design. A research software model is introduced. This software model mainly deals with why and how extensions to existing PDM systems by adding CSCW and RBAC mechanism. In order to comprehend easily, this paper first discusses the conception of PDM, CSCW and RBAC. Then the main idea, the architecture of software framework architecture model is presented.
