摘要
通过分析产品数据权限管理相关对象及其它们之间的关系,介绍了基于角色的产品数据存取控制模型,并分析其优点和不足.在此基础上,本文提出了基于任务和角色的复合产品数据权限管理模型,详细讨论了数据存取权限的类型,研究了产品开发流程中的动态权限控制,最后给出了产品数据存取权限的计算过程.
This paper introduces the role-based access control model(RACM),and the advantage and disadvantage of RACM are indicated.After analyzing access control objects and relations among them in collaborative product development process(CPDP),task-role-based authority management model(TAMM)is proposed.Dynamic right control in CPDP is studied and access right types for product data are given.Finally dynamic right computation process in TAMM is proposed.
