When you edit a question, does it get saved to the database?

I’d like to make a page that shows each change made to the question grouped by when the user did it. For example, after creating the question the user sees that they misspelled a lot of words. So they edit it. This is Edit#1. Then 1 week later they want to edit it to add an image. This is Edit#2. etc…. My page will show original question, then Edit#1, Edit#2 etc… Is the database set up so that it creates a new row with edited information whenever the question is changed?
