Supplier Management System is a Spring Boot REST backend. A client sends resource requests to controllers, which delegate to services; services apply entity-level checks and operations, then return response-wrapped results. The API covers supplier CRUD plus customer, product, and order management, including relationship and query features such as pagination. Services call DAOs; the supplied repository interfaces use Spring Data JPA, with MySQL documented as the database. DAO-to-repository wiring is not shown in the sampled source, so that link is omitted.
