工作流系统中业务工具动态集成模型研究

Research on dynamic application tools integration model in workflow management system

为增强工作流系统和相关业务工具的集成能力,提出了一种两层活动节点模型。该模型将工作流活动划分为活动控制层和活动业务层,通过各自独立封装来降低两层间的耦合度。给出了控制层与业务层的关联描述模型、活动间数据传递模型、活动内数据传递模型等3种模型。介绍了基于这些模型建立的工作流系统的运行实例,实例表明这些模型增强了流程系统的业务工具动态集成能力。

To improve the flexibility of integration between workflow system and its relevant application tools, a two-level activity model was proposed. In the model, workflow activities were divided into control layer and business logic layer. Coupling index of these two layers was reduced by independent encapsulation of the two layers. Relation model between the two layers, data transmission model among activities, and data transmission model in activity were provided. Finally, an application example was introduced to testify the model＇s ability to dynamically integrate application tools.
