Example

Insurance claim handling across business processes, application services, and infrastructure:

@startuml
!include <archimate/Archimate>

rectangle "Business Layer" {
  Business_Actor(customer, "Customer")
  Business_Actor(agent, "Claims Agent")
  Business_Process(submit, "Submit Claim")
  Business_Process(assess, "Assess Claim")
  Business_Process(pay, "Process Payment")
  Business_Service(claimSvc, "Claims Service")
  Business_Service(paySvc, "Payment Service")
}

rectangle "Application Layer" {
  Application_Component(claimApp, "Claims System")
  Application_Component(crmApp, "CRM System")
  Application_Component(finApp, "Finance System")
  Application_Service(claimAPI, "Claims API")
  Application_Service(custAPI, "Customer API")
  Application_Service(payAPI, "Payment API")
  Application_DataObject(claimData, "Claim Record")
  Application_DataObject(custData, "Customer Profile")
}

rectangle "Technology Layer" {
  Technology_Node(appSrv, "Application Server")
  Technology_Node(webSrv, "Web Server")
  Technology_Device(dbSrv, "Database Server")

Pattern Notes

Three-layer structure — rectangle "Business Layer", "Application Layer", "Technology Layer" map to core ArchiMate layers
Realization — Rel_Realization links business processes to services, and application components to application services
Serving — Rel_Serving shows application services serving business services (upward dependency)
Assignment — Rel_Assignment assigns technology nodes to application components (hosting relationship)
Triggering chain — Rel_Triggering creates the sequential flow: Submit → Assess → Pay
Data objects — Application_DataObject with Rel_Access shows which components read/write which data
