I wouldn't recommend it, I've seen it abused as a database a few times and it was never good. It really is barebones and mostly for content and the UI/features show that.

You're better of using anything else, if you want a UI ontop maybe a tool like Pocketbase is better suited or you go the route of using an actual e-commerce tool like Saleor or Medusa.

Both are good, definitely better than homebrewing your database and that is >>> any open source CMS (I've tried a few dozen since I am building a CMS myself)
