## Overview

This repository contains three separate Spring Boot examples: a department–employee one-to-many mapping, a basic website, and a book-management application. The book app’s documented user journey covers registration and login, followed by book creation, listing, updating, and deletion; the README also identifies JWT-based security. The graph preserves the major capabilities and separates the examples. Source excerpts are available only for the mapping entities and a website script, so wiring between controllers, services, and repositories is omitted where it cannot be verified.
