摘    要:根据数据流模型的特点定义了数据流元模型,创建了能够准确描述活动问细粒度接口数据交互的数据流二步建模法,并为其提供了一种图形表示;扩展传统工作流引擎,提出了活动多实例工作流中数据流的调度策略,以及根据数据一致性验证准则实现了数据准备、数据提交等关键调度算法,进而提出的虚拟活动实例概念解决了活动实例数据多版本的管理问题.最后通过应用实例对文中的理论进行了验证.

关 键 词:工作流  数据流  活动多实例  建模  调度  一致性

Abstract:According to the characteristics of data flow model,a data flow meta-model is defined and a graphical two-step modeling method of data flows is presented,which can exactly describe interactions among fine-grained interface data between activities.Through extension of the traditional workflow engine,scheduling policy of data flows in workflow of activity instances is presented,and the key scheduling algorithms are realized according to the validation rule of data consistency,such as data preparation and data...
Keywords:workflow  data flow  activity instances  modeling  scheduling  consistency
