A special form of data-flow plan is a site-oriented data-flow plan. Data-flow diagrams can be regarded as inverted Petri nets, because places in such networks ...
Activity diagrams can be regarded as a form of a structured flowchart combined with a traditional data flow diagram. Typical flowchart techniques lack constructs for expressing concurrency.

[2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
A lane contains the flow objects, connecting objects and artifacts. Artifacts allow developers to bring some more information into the model/diagram. In this way the model/diagram becomes more readable. There are three pre-defined Artifacts, and they are: Data objects: Data objects show the reader which data is required or produced in an activity.
