Review Summary
Your schema demonstrates excellent understanding of 3NF normalization with properly structured tables and foreign key relationships. However, the script is missing the required DROP DATABASE ShopDB; statement at the beginning, which is explicitly mandated by the task requirements and testing steps. Add DROP DATABASE IF EXISTS ShopDB; before your CREATE DATABASE statement—this ensures a clean state for testing and matches the specified prerequisites. Once this single statement is added, your implementation will be complete. The normalization work you did is solid; this is just a missing requirement.

Review Summary
Your solution is approved. The database has been successfully normalized from 1NF to 3NF with four well-structured tables (Countries, Products, Warehouses, ProductInventory) and proper foreign key relationships. The DROP DATABASE IF EXISTS ShopDB; statement is present, all primary and foreign keys are correctly defined, and the INSERT statements properly populate the normalized data structure. All requirements from the task are met with no critical issues identified.
