🛒 E-Commerce Management System (Educational Edition)

This project simulates a simplified backend system of an e-commerce platform designed to teach advanced object-oriented programming (OOP) and MVC-style architecture using pure Python.

---

📚 Project Purpose

This system is built who want to:

• Deepen their understanding of OOP principles.
• Learn how to structure code using a controller-like architecture (similar to MVC).
• Understand how real-world systems like shopping carts, orders, users, and payments are modeled.
