# Session 1: Project Setup for [E-Commerce Website]

## Context
- **Project Name**: E-Commerce Website
- **Language**: Python with Django
- **Key Requirements**: User authentication, product catalog, shopping cart

## Task: Database Schema Design

Based on the requirements, here's a proposed database schema:

```sql
CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    username VARCHAR(50) UNIQUE NOT NULL,
    email VARCHAR(100) UNIQUE NOT NULL,
    password_hash VARCHAR(255) NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE products (
    id SERIAL PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    description TEXT,
    price DECIMAL(10, 2) NOT NULL,
    stock_quantity INTEGER NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE carts (
    id SERIAL PRIMARY KEY,
    user_id INTEGER REFERENCES users(id),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE cart_items (
    id SERIAL PRIMARY KEY,
    cart_id INTEGER REFERENCES carts(id),
    product_id INTEGER REFERENCES products(id),
    quantity INTEGER NOT NULL,
    added_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
```

## Next Steps
1. Review the schema and suggest any modifications
2. Discuss the authentication flow
3. Plan the product catalog interface
