# run this service domain standalone
git clone https://github.com/Sreenivas-Sadhu-Prabhakara/sd-account-reconciliation
mvn -f sd-account-reconciliation spring-boot:run
curl localhost:8080/v1/service-domain

# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-account-reconciliation ./helm -n bian-operations

FAQQuestions

What is the BIAN “Process” functional pattern?
A Process service domain executes and tracks a defined operational procedure, step by step, to completion. Account Reconciliation applies it to the Account Reconciliation.
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. Account Reconciliation is the service domain for Operations; it manages the Account Reconciliation Procedure and exposes it through standard BIAN action terms.
What business area does Account Reconciliation belong to?
Account Reconciliation 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 Account Reconciliation 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.
