## Overview

This is a Spring Boot student-management API. Clients submit student requests to the REST controller, which maps and validates input, delegates CRUD and search operations to a service, and returns mapped responses. The service uses a JPA repository to access student records; the API also exposes name/age searches and pagination. The README is empty, so capabilities and relationships here are based on the sampled source and tree; database configuration and other controllers were not inspected.
