Review Summary

The test validation is failing because the database schema doesn't match the expected structure. The errors indicate too many or too few tables were created and incorrect foreign key relationships in the ProductInventory table. Your normalization approach (Countries→Cities→Streets→Warehouses) is conceptually correct, but the actual table count or foreign key definitions don't align with what the test expects. Additionally, the script is missing the required DROP DATABASE ShopDB; statement at the beginning [CHECKLIST ITEM #4] for a clean state. Please review the test expectations for the exact number of tables required and ensure the ProductInventory table has the correct foreign key relationships to parent tables.

Review Summary

The database schema validation tests are failing due to two critical issues: (1) incorrect table count - your current 3-table structure (Countries, Warehouses, ProductInventory) doesn't match what the test expects, and (2) incorrect foreign key count in the ProductInventory table. While your normalization approach to 3NF is conceptually sound, the implementation doesn't align with the test requirements. You need to adjust your table structure to match the expected schema - this likely means either adding intermediate tables (such as a Products table or separate location tables) or modifying how you've decomposed the original schema. Check the test expectations carefully and ensure ProductInventory has the correct foreign key relationships to match the validation criteria. Your solution correctly includes the DROP DATABASE statement [CHECKLIST ITEM #4] and properly implements Countries and Warehouses tables, but the overall schema decomposition needs to be revised to pass the tests.

Review Summary

Your schema now correctly implements 4-table normalization to 3NF with proper foreign key relationships between Countries, Warehouses, Products, and ProductInventory tables. The DROP DATABASE ShopDB; statement is included, test data is properly populated, and all functional requirements are met. Well done on identifying and fixing the previous table count and foreign key issues—your implementation should now pass validation tests.
