    This section provides you with general information about workflows, from information you need to develop them to running them.
    - Tasks
      Workflow tasks are accessible when a workflow has been put into a run time state. When a workflow is running, the task information is available to the computers and operators assigned to that task or task step, as well as to administrators.
    - Workflow Execution Engine Overview
      This application consists of a workflow execution engine, which is the core component of the process management system. The engine is responsible for interpreting workflows, controlling multiple workflow instances, and sequencing subprocesses and activities.

    - Building and Configuring Workflows
      Workflows consist of programs that can carry out complex activities, respond to events and data changes, and write values back out to the data models or through external connectors.
    - Process Execution Model Overview
      The process execution model defines the structure of a workflow, and has several process steps that can be programmed and triggered during a workflow instance.

Persistence in Workflows

The execution engine records internal tracking data in worflows that includes the state information associated with a running workflow instance. The execution engine persists the workflow instance state when a subprocess completes. The persisted state can be used to recover and restart a workflow instance from failure conditions, or if it was stopped. If a workflow is stopped normally, the postsubprocess, postprocess, and unload steps run before the instance stops (they will not run if the server crashes). The workflow instance can continue from the start of the current subprocess by using the restart command. When this happens, the instance restarts by running the load, preprocess, and presubprocess steps. Then it restarts at the beginning of the subprocess that was running before the workflow stopped.
