Here is a new blank database:
Database Name: MyNewDatabase
Tables:

(varchar)password
(varchar)
products
id
(primary key, integer)name
(varchar)description
(text)price
(decimal)
orders
id
(primary key, integer)user_id
(foreign key referencingusers.id
)order_date
(datetime)total
(decimal)
order_items

(primary key, integer)order_id
(foreign key referencingorders.id

Relationships:
- A user can have many orders (one-to-many).
- An order is associated with one user (many-to-one).
- An order can have many order items (one-to-many).
- An order item is associated with one order and one product (many-to-one).
Data Types:

This is just a starting point, and you can add or modify tables, fields, and relationships as needed to fit your specific use case.
