Process/System Realization Diagrams and UML/BPMN EAP Profile Overview
The article explains the purpose and components of process/system realization diagrams, introduces the UML/BPMN EAP profile and Archimate examples, and includes references and promotional links for enterprise architecture communities.
Process/system realization diagrams aim to clearly describe the sequence of events when a business process involves multiple applications, enhancing communication diagrams, adding ordering constraints, and identifying handoff points between batch and real‑time processing, while revealing simplification and rationalization opportunities to improve information timeliness and reduce inter‑application traffic.
UML/BPMN EAP Profile
Interaction Application Component : Represents the top‑level component that manages interaction with external elements of the information system, typically a GUI such as a web interface.
Process Application Component : Responsible for executing business processes and orchestrating their tasks.
Business Process : Depicted in flowcharts (event diagrams) with detailed specifications.
Application : Corresponds to legacy systems, off‑the‑shelf products, or an assembly of application components.
Component Implementation : Specifies the concrete elements of an application component, such as a business process.
Access Link : Shows dependencies between parts of the information system, usually between application components, indicating that a source element uses or accesses a target element.
Information Flow : Defines any type of information flow (business entities, events, products, informal information, etc.) between enterprise activity entities.
Archimate
Two processes are realized by one application and two application components.
The BookTravel process is initiated by the travel‑booking site and executed by the “BookTravel” process application component.
