Bank Loan Application Sequence Diagram

This Sequence Diagram is used to map how a bank loan application moves from the Applicant through the Loan Portal, Loan DB, Underwriting Engine, and Credit Bureau to an approval outcome. It helps teams understand submission, data storage, credit report retrieval, risk assessment, decision updates, and applicant notification, making handoffs and dependencies clear for product managers, solution architects, developers, QA analysts, and banking operations teams.
