[Anime] Dragonball, where to start?

Hey

I've been thinking about watching Dragonball, but when I searched it up it was alot of different shows.. I've heard about Dragonball Z, and thought that was the name of the show. But is it like in Naruto, where you got Naruto then Naruto Shippuden where he's older? And thus I need to watch Dragonball, Dragonball GT and then Dragonball Z?

Thanks for the replies.
