🧩 BUILDING A CUSTOM ORM IN PYTHON

This project is a mini ORM engine built from scratch in python. It simulates how real ORMs like Django ORM / SQLAlchemy works internally.

It allows me to:

• Pretend Python lists are database tables
• Create tables
• Insert data
• Query data
• Update and delete data
• Understand relationships (Student --> Teacher)

🏫 A MINI ORM FOR SCHOOL MANAGEMENT SYSTEM

This ORM is built around a simple school system with:

• Students
• Techers
• A Relationship between them

├── database.py   # Fake database (tables + storage)
├── models.py     # Table → Class mapping & insert logic

├── main.py       # Run & test the ORM

🔁 Project Flow

database.py → defines tables
models.py   → inserts data using ORM
query.py    → fetches / filters data
main.py     → runs the project

⚙️ How it Works

1️⃣ database.py

Stores fake tables using python lists and simulates auto-increment IDs.

2️⃣ models.py

Maps tables to classes (Student, Teacher) and handles inserts.

3️⃣ query.py

Acts like a query engine (Similar to SQL SELECT, UPDATE, DELETE).

4️⃣ main.py

This is the entry point where data is created and queried.
