Business Rules and Orchestrations
- You can incorporate business rules within your orchestration to allow flexibility to read and process constantly changing values instead of having to recode/recompile the orchestration
- Based on a business rule, you can determine when a process requires a delay
Steps to integrate business rules are as follows:
- Identify the business logic to be represented
- Identify data sources for rule elements
- Create rules from vocabulary definitions
- Test and debug with facts
- Publish and deploy policy
- Bind send and receive shapes to ports
- Call the rule from within an orchestration
Steps to integrate business rules with an orchestration are as follows:
- Add a reference to the rule engine assembly
- Make the orchestration transactional
- Add an atomic scope
- Add a message assignment shape
- Create a message instance
