Database Entity Relationship Diagram

This ER diagram models the core tables and relationships behind a typical e-commerce database, from customers and orders to inventory and reviews. It's a solid starting point for database design or documentation projects. Tip: normalize your entities first on paper, then use the diagram to validate that every relationship has correct cardinality.
