Research of Compound Data Right Control Basde on Flow
基于流程的复合数据权限控制研究

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.
