About This Architecture

Users and Orders ER diagram models a one-to-many relationship between user accounts and customer orders using relational database design principles. The users table stores authentication credentials, contact information, and verification status with id as primary key and unique constraints on phone and email fields. The orders table captures order details including user_id as a foreign key linking back to users, enabling efficient queries across customer purchase history. This schema demonstrates normalized database design that prevents data duplication while maintaining referential integrity across user and order records. Fork this diagram on Diagrams.so to customize field types, add order status tracking, or extend with payment and shipping tables for your application.
