Review Summary
Your 3NF normalization implementation is technically sound—Products, Countries, Warehouses, and the junction ProductInventory table are correctly structured with proper foreign keys. However, changes are required because the task checklist explicitly requires a DROP DATABASE ShopDB; statement before CREATE DATABASE ShopDB; to remove any existing database from previous tasks. This is listed as a critical blocker that prevents requirement compliance. Please add DROP DATABASE IF EXISTS ShopDB; at the very beginning of your SQL file before the CREATE DATABASE statement. Once this single statement is added, your submission will meet all requirements.

Review Summary
Your implementation is approved. The database has been successfully normalized to 3NF with four properly structured tables (Products, Countries, Warehouses, ProductInventory) and correct foreign key relationships. The previously requested DROP DATABASE IF EXISTS ShopDB; statement has been added at line 1, and all test data maintains consistent relationships across the normalized structure. No critical issues remain.
