It makes sense that an analyst would just shift through internal tools not connected, that process intelligence data.

However, they must have s/w engineers. I'm curious how they do their jobs w/o stack-overflow, google and obviously HN. :)

Yes, it's possible to do dev w/o an internet connection, but programming nowadays is a pita, especially as a full-stacker. i.e. I just had to deal with a sticky css footer problem and I would have topped myself if I didn't have the internet.
