About This Architecture

Online gaming store ER diagram models a normalized relational schema with seven core entities: USERS, GAMES, ORDERS, ORDER_ITEMS, REVIEWS, CATEGORIES, and GENRES. Data flows from USERS through ORDERS and ORDER_ITEMS to GAMES, with REVIEWS linking users and games bidirectionally, while CATEGORIES and GENRES classify games via foreign keys. This schema enforces referential integrity and separates concerns—order line items, user reviews, and game metadata—enabling efficient queries for inventory, sales, and user engagement analytics. Fork this diagram on Diagrams.so to customize table structures, add indexes, or adapt it for your gaming platform's specific requirements. Consider adding a WISHLIST entity or payment status tracking if your store requires advanced features.
