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

helm upgrade --install sd-systems-administration ./helm -n bian-business-support

FAQQuestions

What is the BIAN “Administer” functional pattern?
An Administer service domain maintains and applies administrative rules, agreements or records over time. Systems Administration applies it to the System Configuration.
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. Systems Administration is the service domain for Technology and Operations; it manages the System Configuration Administrative Plan and exposes it through standard BIAN action terms.
What business area does Systems Administration belong to?
Systems Administration 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 Systems Administration 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.
