Build database from app?

Hello, new to Retool - exploring this as a possible database entry solution for my org.

I've been building in Retool since the end of last week and have created some great visuals with the app building module - very well fleshed out and easy to use. While I understand this is a form, I'd like to use this to create a database in the background for submissions. My reading of the Retool docs shows where you can create a form from a database, but is there some setup I'm missing that can create a database from the form? I can create a CSV to make a database and then recreate the form but would rather use to the more stylistic setup of my app and not redo the work if possible.

Thank you!
