RUNRun it yourself

Each service domain is its own standalone Spring Boot repository — clone and run in seconds, or deploy onto Kubernetes with the bundled Helm chart behind the Cilium mesh.

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

# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-procurement ./helm -n bian-business-support

FAQQuestions

What is the BIAN “Process” functional pattern?
A Process service domain executes and tracks a defined operational procedure, step by step, to completion. Procurement applies it to the Purchase Order.
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. Procurement is the service domain for Corporate Services; it manages the Purchase Order Procedure and exposes it through standard BIAN action terms.
What business area does Procurement belong to?
Procurement sits in the Business Support business area — the shared corporate, finance and technology domains that run the bank itself. It runs in the bian-business-support namespace as one independent Spring Boot microservice.
Is Procurement 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.
