FAQQuestions
What is the BIAN “Fulfill” functional pattern?
A Fulfill service domain runs the full lifecycle of a product or service arrangement — origination, servicing and closure. Reward Points Account applies it to the Reward Points Facility.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Reward Points Account is the service domain for Account Management; it manages the Reward Points Facility Fulfillment Arrangement and exposes it through standard BIAN action terms.
What business area does Reward Points Account belong to?
Reward Points Account sits in the Operations and Execution business area — the operational core that executes payments, positions, settlements and transactions. It runs in the bian-operations namespace as one independent Spring Boot microservice.
Is Reward Points Account production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
