Workflow Sketch

Workflows represent data analysis processes as a graph of tasks connected by the dataflow among them. As an example, consider a prototypical workflow for calculating whole stream metabolism integrating dissolved oxygen and temperature sensor time series data with ancillary data on the photoperiod and stream flow conditions. A sketch depicting the workflow is as follows:

Computational workflow

Workflow systems can represent workflows of analytic steps capture and manage their execution automatically and efficiently. Here is a workflow with the computations in the sketch above, showing parallel processing of datasets:

Executing this workflow produces the following result:
