 基于PLM系统中影响数据权限的4种因素,提出了基于权限规则的动态权限控制机制。为了使数据对象的生命周期模板在组织结构变化的情况下不改变结构,提出了数据权限在数据对象外部映射的思想。主要研究了解决复杂数据权限的问题,最后验证此权限模型的正确性和通用性。

Abstract:
 Four factors which affect the data permission in the PLM system were investigated in this study. On the basis, the dynamic access control mechanism that based on permission rules was proposed. In order to make the life cycle template of data object keep unchanged structure on the condition that the organizational structure changed, the thought of data permission mapping outside the data subjects was put forward. The main purpose of this study is to solve complex data permission issues and verify whether the permission model is correct and universal or not.
