Review Summary

Your solution successfully normalizes the ShopDB database from 1NF to 3NF. The schema correctly separates the original structure into four tables: Countries, Products, Warehouses, and ProductInventory, with proper foreign key relationships that maintain data integrity. The INSERT statements properly populate all normalized tables with equivalent test data while supporting multiple warehouses with varying product quantities per warehouse. The implementation uses MySQL-compatible syntax throughout with appropriate PRIMARY KEY and FOREIGN KEY constraints. All requirements from the task have been met, so your work is approved.
