## Overview

This is a small Spring Boot ERP application with home, item-listing, and member-query routes. The item route reads an in-memory item store and supplies a server-rendered view; the member route returns mapper results directly. A separate member service also delegates to the mapper, but the sampled controller does not use that service. Relationships below are limited to sampled calls and the mapper’s explicit SQL; the README is empty, so broader ERP capabilities cannot be established.
