【摘要】 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。更多还原

【Abstract】 The compound data right control was realized merely by role in the past.Its right in each stage is the static state,but the data is in during the dynamic change in the coordination performance history.Therefore the user right also should be dynamic.This article has analyzed the data right management correlation objects and the relations between them,introduced based on the article proposed compound data right model based on the flow,has studied dynamic right control in the flow,and finally has produced the data right computation process.更多还原
