How do I design a SQL database for my application?

To design a SQL database, start by identifying the entities and relationships in your application. What are the main components?

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

You can create three tables: Users, Products, and Orders. Users can have a one-to-many relationship with Orders, and each Order can reference a Product.

What fields should I include in each table?

For Users, include fields like user_id, name, and email. For Products, use product_id, name, and price. For Orders, include order_id, user_id, and product_id.

How do I ensure data integrity in my database?

Use primary keys for unique identification, foreign keys for relationships, and consider using constraints to enforce data rules.
