Electron is fine for a PoS if the computer is secure otherwise and you don’t handle payments through it (use an online processor like Stripe or Square for card transactions).

You can use whatever style of database you want. If there’s a Node package available for it, you should be able to use it. For example, if you wanted to use MongoDB, you’d install the mongodb package.
