Abstract
Designing and analyzing business processes is the starting point of the development of enterprise applications, especially when following the SOA (Service Oriented Architecture) paradigm. UML activity diagrams are often used to model business processes. Unfortunately, their rich syntax favors mistakes by designers; furthermore, their informal semantics prevents the use of automated verification techniques. In this paper, (i) we propose activity diagram patterns for modeling business processes, (ii) we devise a modular mechanism to compose diagram fragments into a UML activity diagram, and (iii) we propose a semantics for the produced activity diagrams, formalized by colored Petri nets. Our approach guides the modeler task (helping to avoid common mistakes), and allows for automated verification.KeywordsBusiness ProcessGlobal VariableService Orient ArchitectureActivity DiagramProcess ParticipantThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
