摘要
将工作流模型划分为三部分:过程模型、数据模型、组织模型。通过ECA规则与有向图相结合对工作流进行过程建模,利用有向图直观地表述流程的走向,工作流引擎通过对ECA规则的解释导航流程;给出了数据模型中数据对象的形式化定义;在组织模型中对RBAC模型进行改进,解决其在细粒度权限控制上的不足。
The workflow model is divided into three parts: process model, data model and organization model. The process is modeled based on restricted digraph and ECA rules. The flow is intuitively described by the digraph and the flow is navigated by the interpreting of ECA from the workflow engine. The formalization definition of data model is presented. The improved RBAC model is put forward in organization model and it can make up the deficiency on small granular information control.
