How do I design an SQL database schema for my application?

To design an SQL database schema, start by identifying the entities and their relationships. What are the main components of your application?

I have users, products, and orders. How should I structure these?

You can create three tables: Users, Products, and Orders. The Users table can have user_id, name, and email. Products can have product_id, name, and price. Orders can link users and products with order_id, user_id, and product_id.

What about relationships between these tables?

You should establish foreign keys. For example, in the Orders table, user_id should reference Users, and product_id should reference Products. This enforces the relationship between them.
