Definition

Data that is managed by the Workflow Management System and/or a Workflow Engine. Such data is internal to the workflow management system and is not normally accessible to applications.

Key Points

Workflow control data represents the dynamic state of the workflow system and its process instances.

Workflow control data examples include:
  • State information about each workflow instance.

  • State information about each activity instance (active or inactive).

  • Information on recovery and restart points within each process, etc.

The workflow control data may be written to persistent storage periodically to facilitate restart and recovery of the system after failure. It may also be used to derive audit data.
