  • Summary:

    The representation of "Example of Activity Diagram" is weird. It mixes data
    flow and control flow.

    Between two activities there should be a plain arrow if one comes after the
    other, and not a dashed arrow going from the 1st activity to an artifact and
    then another dashed arrow going from the artifact to the second activity. The
    fact that one activity comes after another is a control flow, the fact that a
    part from that one artifact is passing from one to the other is different.

    Because of this confusion, the strangest thing happens: synchronization bars
    are showed to synchronize activities with artifacts! This has no meaning.
    Only plain arroaw should leave and arrive to synchronization bars. They would
    go to or from activities, showing that two activities happen concurrently.
    The flow of data between the activities (artifacts and dashed arrows are
    something different)
