Designing a database schema for an online merch store involves identifying the entities, relationships, and attributes relevant to the application. Be

1.

Products Table:
– ProductID (Primary Key)
– ProductName
– Description
– Price
– StockQuantity
– CategoryID (Foreign Key referencing Categories table)

2. Categories Table:

– CategoryID (Primary Key)
– CategoryName

3. Customers Table:

– CustomerID (Primary Key)
– FirstName
– LastName
– Email
– Password
– Address
– Phone

4. Orders Table:

– OrderID (Primary Key)
– CustomerID (Foreign Key referencing Customers table)
– OrderDate
– TotalAmount

5. OrderItems Table:

– OrderItemID (Primary Key)
– OrderID (Foreign Key referencing Orders table)
– ProductID (Foreign Key referencing Products table)
– Quantity
– Subtotal

This schema assumes a few things:
– Each product belongs to a specific category.

– Each customer has a unique identifier and can place multiple orders.
– Each order has multiple order items, representing the products included in that order.
– The OrderItems table contains information about the quantity and subtotal for each product in an order.
You can expand on this schema based on additional features you may want to include in your online merch store. For example, you might want to add tables for reviews, discounts, or shipping information. Additionally, consider incorporating data types, constraints, and indexes to ensure data integrity and improve query performance.
