helm upgrade --install sd-e-branch-operation ./helm -n bian-sales-service

FAQQuestions

What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. E-Branch Operation applies it to the Digital Branch Session.
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. E-Branch Operation is the service domain for Channels; it manages the Digital Branch Session Operating Session and exposes it through standard BIAN action terms.
What business area does E-Branch Operation belong to?
E-Branch Operation sits in the Sales and Service business area — the customer-facing sales, servicing and channel domains that run the customer lifecycle. It runs in the bian-sales-service namespace as one independent Spring Boot microservice.
Is E-Branch Operation 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.
