FAQQuestions

What is the BIAN “Assess” functional pattern?
An Assess service domain evaluates a case, application or exposure against criteria and returns a decision or rating. Customer Credit Rating applies it to the Credit Rating.
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. Customer Credit Rating is the service domain for Credit Risk; it manages the Credit Rating Assessment and exposes it through standard BIAN action terms.
What business area does Customer Credit Rating belong to?
Customer Credit Rating sits in the Risk and Compliance business area — the risk, financial-crime and regulatory-compliance domains that keep the bank safe and compliant. It runs in the bian-risk-compliance namespace as one independent Spring Boot microservice.
Is Customer Credit Rating 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.
