Before we move on, let's talk about an important topic. Consider that we have two work-
flows: wf_WORKFLOW1 and wf_WORKFLOW2 . The Wf_WORKFLOW1 workflow con-
tains the session task and the command task. We have a requirement in which
wf_WORKFLOW1 triggers wf_WORKFLOW2 upon successful completion.
For the session task and the command task, wf_WORKFLOW1 will be called the parent
workflow.
For wf_WORKFLOW2 , wf_WORKFLOW1 will be called the top-level workflow, because
wf_WORKFLOW1 triggers wf_WORKFLOW2 .
