E-Commerce Project (Part 2) — Entity Creation & Complete Database Modeling

In this second episode of our E-Commerce Project Series, we move from planning to architecture.
Here, we shape the foundation of the entire system by designing clean, scalable, and production-ready entities.

This is the stage where your backend takes its first real form — where structure becomes strategy.

👉 In this video, you will learn:

✔ How to create entities for Users, Orders, Products, Cart & Payments
✔ How to design enums for role, order status, payment method, and payment status
✔ Mapping relationships:
• One-to-Many
• Many-to-One
• One-to-One
✔ Choosing between LAZY vs EAGER fetch
✔ Understanding database normalization through real e-commerce flows
✔ Writing entities that scale like a production system
