What is the design of a database cal
This schema includes the following relationships:
- One-to-Many relationship between User and Order (One user can place many orders).
- One-to-Many relationship between Order and OrderItem (One order can contain multiple order items).
- One-to-Many relationship between Product and OrderItem (One product can appear in multiple order items).
- One-to-Many relationship between User and Cart (One user can have one shopping cart).
- One-to-Many relationship between Cart and CartItem (One shopping cart can contain multiple items).
You may need additional tables or fields based on your specific requirements. For example, if you want to handle product reviews, you might need a "Review" table with fields like ReviewID, UserID, ProductID, Rating, and Comment. Additionally, consider incorporating security measures such as password hashing and encryption based on best practices for user authentication.
