"Could you help me to edit the SQL code for the ER diagram I've created with visuals?
Basically, the scenario of the system is as follows:
A user scans a QR code. After scanning the QR code, they can access a menu interface where they can navigate through categories and view products. Additionally, within the menu, the address and contact information of the venue are provided. Furthermore, QR codes are specific to tables, allowing payments to be attributed to the respective tables, and customers can make payments through the interface. Waiters are responsible for bringing and delivering orders. Also, users can leave comments through the interface and receive recommendations from artificial intelligence. You can make any necessary additions you see fit and adjust the code accordingly. Please either correct the SQL code or provide a different output for the ER diagram."
Here is my sql code for the er diagram visual that i added.
CREATE TABLE Profile
