Platform Overview

The Banking System simulates common retail banking flows such as customer onboarding, multi-account management, and transaction processing. Core capabilities include:

• Customer and account lifecycle management with Savings, Current, and Fixed Deposit account types.
• Transaction execution for deposits, withdrawals, transfers, interest postings, and audit trails.
• Console and HTTP interfaces backed by the shared domain model for teller workflows and automation.
• Observability hooks via notifiers and loggers that react to account events.
• Persistence and caching abstraction layers supporting in-memory demos and JDBC-backed deployments.

For deeper background, review the Architecture Summary or the existing reference documents in docs/.
