• REST APIs for providing data to UIs
  • Provides REST services, by utilzing 1) Camunda REST APIs, such as BPMN XML string, process activity data, process variable, statistic, and 2) SO Request DB APIs for a service list.
  • Consolidate data responses from multpile Camunda calls and feed them to UIs.
  • Use of HistoryService APIs, example, processEngine.getHistoryService().createHistoricProcessVariableQuery().xyz
  • Set a History level to ACTIVITY as a minimum; AUDIT (default) level for process variable tracing
  • Provides workflow tracing (between parent-child workflows, interaction with other services; service task in and out); example,
    • processEngine.getRuntimeService().createExecutionQuery().processVariableValueEquals("serviceInstanceId", serviceInstanceId).singleResult();
  • Custom Query
    • Custom Query against History ACT_HI_DETAIL database table, as needed
• Custom History Event Producer
  • Populate additional data in history with extensibility

• • Estimates
  • Note: 
    • It is a rough estimate - to be refined
    • Estimate includes development and unit testing time
