Abstract

Both control-flow and data-flow perspectives are primary in process representation of a workflow. Data-flow perspective is always layered on top of the control-flow perspective. Since process representation from the data-flow perspective is more stable than from the control-flow perspective, in this paper, a data-flow skeleton from data-flow perspective is placed as the base in workflow design. The complete procedures of this approach to design a workflow is elaborated. The structure of data-flow skeletons is deduced automatically and two properties of data-flow dependency trees are presented. Workflows designed based on data-flow skeletons are free of data anomalies, among some other virtues.
