using in game and backend Database in Unreal Engine

Hello Everyone, I am a game developer who had an idea for a project in mind an MMORPG project (or at the very least it’s beginning) and it will require using Database such as SQL (which I tend to preferer, particularly MySQL) for in games data such as Classes, Races, Equipment, Spells and Skills, I would also need another one for backend users and characters data.

So do you have any recommendation? is MySQL good for such things or do you recommend something else maybe?
