Online data or streaming data are getting more
and more important for enterprise information systems, e.g. by integrating sensor data and workflows. The continuous flow of data provided e.g. by sensors requires new workflow models addressing the data perspective of these applications, since continuous data is potentially infinite while business process instances are always finite.
In this paper a formal workflow model is proposed with
data driven coordination and explicating properties of the
continuous data processing. These properties can be used
to optimize data workflows, i.e., reducing the computational
power for processing the workflows in an engine by reusing
intermediate processing results in several workflows.
