- 15. 1510/26/2017 Solution idea (high level) BPMCon 2017 – DMN on Steroids Use the advantages of DMN Authorized user can maintain the assignment rules via the business- application • custom authorization • known look and feel • custom proposal lists • custom validation • no knowledge about DMN needed • technical “details” are hidden System generates DMN tables • based on business-rules
- 16. 1610/26/2017 Solution BPMCon 2017 – DMN on Steroids DMN-Generation is triggered when a rule is added, changed or removed Usage of the camunda DMN model API written in Java • rules are processed in the order of the hierarchy • expressions are inherited from parent • each rule can contain multiple expressions Generated DMN is deployed to the engine via RepositoryService DMN evaluation is embedded within a task-assignment process • BPMN-Process as a function (synchronous) • Usage of the camunda-bpm-reactor1 extension • Wrap delegate calls with new transaction 1: https://github.com/camunda/camunda-bpm-reactor
