Review Summary

I am approving your solution because your task.sql script correctly creates the ShopDB database and defines all four required tables (Products, Customers, Orders, OrderItems) with the specified columns and allowed data types. You set primary keys on each ID column using AUTO_INCREMENT and implemented all required foreign key relationships with ON DELETE SET NULL between Orders -> Customers, OrderItems -> Orders, and OrderItems -> Products, which matches the assignment’s constraints. Functionally, this schema will create the intended online shop structure on a MySQL server without errors and fulfills the core requirements of the task.

The only minor point is the extra SHOW TABLES; statement at the end: it’s not harmful and does not break anything, but in a pure schema file it’s usually omitted to keep the script focused on DDL only. If you want to refine it further, you could remove that line, but this is optional and not required for correctness. Overall, this is a solid, requirement-compliant implementation—well done.
