## Overview

BDTHD is a Java Swing clothing-store system backed by MySQL. Its main customer journey runs from sign-in and role selection through product browsing, cart management, and order placement; staff and administrators use separate management screens for inventory, invoices, people, and reporting. The graph includes major README capabilities even where source was not sampled. Edges are limited to relationships visible in excerpts or the source index, plus README-documented capabilities; unsampled internals are not inferred.

Main entry points: [`src/GUI/Menu.java`](https://github.com/iloveflo/laptrinh_java/blob/main/src/GUI/Menu.java) (Admin menu), [`src/GUI/KhachhangForm.java`](https://github.com/iloveflo/laptrinh_java/blob/main/src/GUI/KhachhangForm.java) (Customer portal), [`src/GUI/Start.java`](https://github.com/iloveflo/laptrinh_java/blob/main/src/GUI/Start.java) (Sign-in screen), [`src/BackEnd/AuthService.java`](https://github.com/iloveflo/laptrinh_java/blob/main/src/BackEnd/AuthService.java) (Authentication)
