Salt and Ice

I know it doesn't really have anything to do with anything we're doing now but something, a question in fact, came into my head due to recent weather activity.

Is the process that makes salt dissolve in water the same as the process that makes salt melt ice? or is it something completely different?

I know it's not particularly constructive in terms of organic chemistry or enthalpy but it's been playing on my mind.
