摘要
将工作流模型划分为三部分:过程模型、数据模型和组织模型。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。设计了模型在J2EE下的部署结构。
The workflow model is divided into three parts:Process Model, Data Model and Organization Model. The Process is modelled based on restricted Digraph and ECA rules. The flow is intuitively described by the Digraph and navigated by workflow engine through interpretation of ECA. The formalization definition of the data object in Data Model is given. The improved RBAC model is put forward in Organization Model and it can make up the deficiency on small granular information control. The deployment of workflow model by J2EE is put forward as well.
