MySQL = shopping cart?

Someone told me MySQL is where you learn how to set up those shopping carts that are on online stores.  I think he is wrong, I'm pretty sure those places must pay a third-party to provide those services.

but while we're on the note, what programming language is used for setting up secure networks for shopping carts- for an online business?

I haven't received any money recently. Maybe you don't know how to apply?
