How to understand which setup class do I need to use and what is it's purpose?

Question

I just started to learn Magento 2 and I'm confused with all those setup classes (eavSetup, categorySetup, Set and so on).

Could someone explain me about those setup classes purposes and how should I know which setup class do I need to use? When should I use eavSetup or categorySetup?

Any information about that would be nice either.

Check this link from Inchoo , they explained M2 setup script very well .

Hope this be helpful for you .
