In which case, I'm sure you must be very happy right now, having just made tons of relationships in the last part! In this part, we'll cover how to: - Add schema definitions to tables and fields - Add constraints and assertions - Make use of the schemafull data patterns using schemafull CRUD Hope you're excited to learn the schemafull way, let's get started.
