What all happens when an item is scanned at the grocery store?

Hello, I hope this is the right place to post this, but the other day I was buying an item as the local grocery store (Giant Eagle in my case) and I started to wonder about how much data gets sent around when a single cashier scans an item. I'm sure data gets sent to all sorts of databases, the manufactor's, the grocer's, marketer's, ect.

If anyone has experience working behind the scenes of one of these big players (Giant Eagle, Wal-Mart, Target, Publix, ect) that could shed some knowledge on this area or point me in the direction to read more about this topic, that would be greatly appreciated. Thanks! :)
