In the beginning you just wanted to move, so you threw together a couple of tables and kept going. It worked. Then six weeks in you needed one user to belong to two teams, and the structure you guessed at could not represent it. Now the fix is not a fix. It is a migration, a rewrite of half your queries, and a weekend you will not get back, all because of a shape you chose in five minutes before you understood the problem.
Data is the layer everything else stands on. Get it wrong and the cost does not stay contained. It spreads into every query, every screen, every feature you build on top of it.
Get the shape right before everything depends on it
The Database tool takes your feature and works out what actually needs to be stored, then generates real MySQL: proper tables, primary keys, foreign keys that keep your data honest, indexes, and the right data types, normalized so you are not duplicating information that will drift out of sync later.
You get the SQL script to run, sample data to test against, and query templates for the common operations, plus a plain-language explanation of why the schema is shaped the way it is. So you are not pasting in something you do not understand. You are starting on a foundation that was designed to hold the weight you are about to put on it.
Build on a foundation that will not crack
The cheapest time to get your data structure right is before you have built anything on top of it. That time is now.
Generate a clean, production-ready database schema for your feature with the Database tool, foreign keys and all.
