MySQL Real-World Projects: E-Commerce Database

E-Commerce Database Schema Overview

An e-commerce database typically includes tables for products, customers, orders, order items, and payments.

Each table stores specific data and connects with others through relationships to maintain data integrity.

• Products table stores details like name, description, price, and stock quantity.
• Customers table holds user information such as name, email, and address.
• Orders table records purchase transactions linked to customers.
• Order Items table tracks individual products within each order.
• Payments table manages payment details and statuses.

Designing Tables and Relationships

Proper table design and relationships are crucial for efficient data retrieval and consistency.

Common relationships include one-to-many between customers and orders, and many-to-many between orders and products via order items.

• Use primary keys to uniquely identify records in each table.
• Foreign keys enforce referential integrity between related tables.
• Many-to-many relationships require junction tables like order_items.

Implementing the E-Commerce Database in MySQL

Let's create the core tables with SQL commands to illustrate the schema implementation.

We will define primary keys, foreign keys, and appropriate data types.
