About This Architecture

E-commerce backend database architecture with normalized relational schema spanning USERS, PRODUCTS, ORDERS, ORDER_ITEMS, and PAYMENTS tables, optimized for transactional integrity and query performance. The Backend API Service orchestrates reads and writes across all tables while Redis Cache layer accelerates frequent product lookups, reducing database load. Foreign key relationships enforce referential integrity between orders and users, order items and products, and payments and orders. This design demonstrates ACID compliance, indexing strategy on primary and foreign keys, and caching patterns essential for high-traffic retail platforms. Fork and customize this diagram on Diagrams.so to adapt table schemas, add audit columns, or extend with inventory management tables.
