Where is post meta data stored

Hey all, we are currently changing theme files and inputing data at the same time. We sometimes have to revert to a previous state when I make a dev mistake on a theme file.

We have a plugin installed called all in one seo. I read that it stores it's edits in the post meta data. Is the post meta data stored in the database?

I ask because I want to make sure that if I revert to old files I don't delete all the hard work one of my team members did inputing the data.
