Designing Database Schemas

Imagine building a house. Before you lay a single brick, you need a blueprint! In databases, that blueprint is called a schema.

A database schema defines the structure of your data. It tells you:

• What tables exist
• What columns each table has
• How different tables are connected

A good schema is key for a well-organized, efficient, and scalable Supabase project.

First, think about the 'things' you want to store. These are your entities. For a social app, entities might be Users, Posts, or Comments.

Next, what details does each entity have? These are its attributes.

• User: name, email, profile picture URL
• Post: title, content, creation date

Listing these helps you imagine your tables.
