Review Summary

Your solution is approved because the SQL script correctly implements all required database structures and constraints for the online shop task. You create the ShopDB database, switch to it, and define all four required tables (Products, Customers, Orders, OrderItems) with the specified columns and only the allowed data types, satisfying [CHECKLIST ITEM #1–6, #9]. All primary keys are INT AUTO_INCREMENT and the foreign key relationships between Orders→Customers and OrderItems→Orders / Products are correctly defined with ON DELETE SET NULL, matching [CHECKLIST ITEM #10–14].

The only minor issue is cosmetic: at the very end of task.sql there appears to be an extra trailing backtick after the final );, which may cause a syntax error in some environments; removing that stray backtick will make the script cleaner and more robust. Non-code requirements such as forking the repository and using a MySQL server/client are process steps outside the script and don’t block approval here. Overall, you’ve met the core schema and constraint requirements well—nice work on implementing a clear and valid database structure.
