复合数据权限控制过去仅仅是通过角色来实现的,其权限在各个阶段是静态的,而在协同开发过程中数据却处于动态变化之中,因此用户权限也应该是动态的。本文分析了数据权限管理相关对象及其间的关系,介绍了基于角色的数据权限控制模型,并分析了优点和不足。在此基础上,文中提出了基于流程的复合数据权限模型,研究了流程中的动态权限控制,最后给出了数据权限的计算过程。
In the past, the authorization of composite data was only realized through the role. The authority of the composite data was static at all stages. However, the data was dynamically changing during the process of collaborative development. Therefore, user authority should also be dynamic. This article analyzes the data rights management related objects and the relationship between them, introduces the role-based data access control model, and analyzes the advantages and disadvantages. On this basis, the author proposes a process-based composite data authority model, studies the dynamic rights control in the process, and finally gives the calculation process of data rights.
