Database design schema for an online merchandise store involves identifying the entities, their attributes, and the relationships between them. Here’s a simplified example to get you started.
Keep in mind that the actual schema may vary based on specific requirements and business needs.
1.Entities.
2.Users.
UserID (Primary Key)
Username
Email
Password
3.Products.
ProductID (Primary Key)
ProductName
Description
Price
StockQuantity
4.Categories.
(Primary Key) Category ID
Name of Category
5.Orders
(Primary Key) order ID
(Foreign userID Key referencing Users.UserID)
Date Order
Total Amount
6.OrderItems.
(Foreign Key referencing Products ID)
Quantity
Subtotal
7.Cart.
CartID (Primary Key)
UserID (Foreign Key referencing Users.UserID)
8.CartItemID

CartItemID

9.Now, let’s describe the relationships.
Users can have multiple orders, but an order belongs to only one user.
Products can belong to multiple categories, and a category can have multiple products.
Orders can have multiple order items, and an order item belongs to only one order.
Products can be part of multiple orders through order items.
Users can have a shopping cart, and a shopping cart can have multiple cart items.
Products can be part of multiple shopping carts through cart items.
This is a basic outline, and you might need to expand or modify it based on additional requirements. Consider adding indexes, constraints, and other optimizations based on the database management system you’re using.
Also, include fields like timestamps for record creation and modification, and any other fields or entities specific to your business needs.
