 This architecture demonstrates a **Java API** (using Spring Boot) connecting to a **PostgreSQL database**, with a **React frontend** consuming the API. The Java API uses Spring Boot with Spring Data JPA and connects to PostgreSQL using JDBC or Spring Data. The React frontend is built with Vite and communicates with the API over HTTP.
