Figure 3.4: An example of UML activity model [107]
merge (diamond), partition/swimlane (line without arrow like a border). The notations
are exemplified in Figure 3.4. Partition/swimlane is normally used to indicate
who/what is performing the activities, which can specify the organizational perspective.
The rest notations can represent the operational/functional and control perspectives.
No particular notations are provided for the phenomena associated with data in UML
Activity Diagram. However, it allows to use texts linked to the flows and activities to
indicate condition, object or message passed in the process. UML Activity Diagram
is often asked to be combined with other UML diagrams to model multiple process
perspectives. For example, UML Use Case Diagram can capture loose collections of
related activities at the high level, which might provide a view of the structural perspective
of processes. After all, the lack of first class process modeling primitives is a
major limitation of UML [26].
3.1.5 BPMN (Business Process Modeling Notation)
BPMN is a new standard of modeling business processes and Web service processes
put forth by the Business Process Management Initiative [126], which is merged with
OMG organization now. BPMN is a semi-formal modeling language providing notations
understandable by business users. Nevertheless, it is also created as visual
