## Overview

This repository contains two JavaFX student-management app variants: a compact FXML-based app and a separate, richer CRUD app with a student form. In the richer variant, users add, edit, or delete students; the app delegates persistence to DAOs and refreshes its table. The sampled code shows the database connection setup and the form’s study-group lookup. DAO internals and the FXML/controller wiring were not sampled, so those relationships are left unspecified.
