Should I use databases?

Hello!
I’m sort of a noob programmer as you’ll see. I don’t know anything about databases and I have no idea if I should use them in my case.
Let’s say I want to make several battle moves (attacks, magic, etc) for a turn based combat game. How should I store all the types of moves? One big XML file? Databases? I really don’t know much about these but I would learn them if I need it.
Thank you!
