## Overview

The repository contains a Django project for managing a modeled production-and-sales domain. The models cover geography and facilities, machines and production operations, products and stock, suppliers and transport, and retail points and invoices. The only implemented user-facing route is Django’s admin; the app’s views are empty. The graph therefore shows admin-driven model management, not an unimplemented operational workflow. Source sampling confirms the model definitions and admin registrations; broader capabilities are inferred from those fields, not from documented behavior.

Main entry points: [`velos/high_level/admin.py`](https://github.com/ahmedchallal54/first_tp/blob/main/velos/high_level/admin.py) (Model registrations), [`velos/db.sqlite3`](https://github.com/ahmedchallal54/first_tp/blob/main/velos/db.sqlite3) (SQLite database), [`velos/velos/urls.py`](https://github.com/ahmedchallal54/first_tp/blob/main/velos/velos/urls.py) (Admin route), [`velos/high_level/models.py`](https://github.com/ahmedchallal54/first_tp/blob/main/velos/high_level/models.py) (Countries, cities, sites)
