FAQQuestions

What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. Financial Message Gateway applies it to the Financial Message.
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. Financial Message Gateway is the service domain for Operations; it manages the Financial Message Operating Session and exposes it through standard BIAN action terms.
What business area does Financial Message Gateway belong to?
Financial Message Gateway 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 Financial Message Gateway 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.
