About This Architecture

Online gaming store entity-relationship diagram modeling a complete marketplace with users, game catalogs, orders, and social features. The schema connects USERS to ORDERS, REVIEWS, and WISHLIST tables, while GAMES link to CATEGORIES, ORDER_ITEMS, REVIEWS, and WISHLIST through foreign keys. This normalized structure supports user authentication, order management, game discovery, and community engagement with mandatory and optional relationships clearly marked. Fork this ERD on Diagrams.so to customize for your gaming platform, add payment processing details, or export as SQL DDL. The design demonstrates best practices for e-commerce databases including audit timestamps, enum status fields, and proper cardinality constraints.

What does a normalized database schema look like for an online gaming store?

This ERD shows a normalized schema with USERS as the central entity connected to ORDERS, REVIEWS, and WISHLIST tables, while GAMES link to CATEGORIES and ORDER_ITEMS. Mandatory relationships (solid lines) enforce referential integrity for critical data like user-order associations, while optional relationships (dashed lines) allow flexible features like wishlists.
