## Overview

This is a PHP music-CD shop with customer account flows, a CD catalog and checkout, plus administrative management pages. The likely customer journey is account access, browsing CDs, preparing an order, and viewing its outcome or history; only parts of that wiring are visible in the sampled source. The graph includes the distinct catalog, checkout, order, and administration areas named by the tree. Database use is explicit in sampled pages; connections among unsampled pages are omitted where their calls or data flow cannot be verified.

Main entry points: [`dashboard.php`](https://github.com/alicialeeyuelin/cd-project/blob/main/dashboard.php) (Shop dashboard), [`index.php`](https://github.com/alicialeeyuelin/cd-project/blob/main/index.php) (Home page), [`registration-form.php`](https://github.com/alicialeeyuelin/cd-project/blob/main/registration-form.php) (Registration form), [`artist-manage.php`](https://github.com/alicialeeyuelin/cd-project/blob/main/artist-manage.php) (Artist management)
