Review Summary

I am approving your solution because your task.sql script cleanly satisfies all the core requirements of the assignment. You created the ShopDB database, defined all four required tables (Products, Customers, Orders, OrderItems), and used only the allowed data types (INT, DATE, VARCHAR(50), VARCHAR(100)) as specified. All primary key ID columns correctly use AUTO_INCREMENT, and the foreign key relationships between Orders → Customers, OrderItems → Orders, and OrderItems → Products are properly set up with ON DELETE SET NULL, which matches the task constraints. There are no functional or structural blockers in your SQL; it should run successfully and produce the expected schema. As minor, optional improvements, you could consider adding NOT NULL constraints where appropriate and possibly adjusting string lengths (e.g., for addresses) based on real-world needs, but these are not required for this task. Overall, you met the checklist items that can be validated in code, and your script is clear and well-structured—nice work.
