I get the use of triggers but can you explain the queue concept?
Let's say I want to be notified every time the count of
an item is increased. How would a queue play into that?
Have a trigger create a record in the event queue, and then have a
process that runs to process the queue (could be a cron, or a daemon)
and send out emails, etc.

Not to discount Matt's solution; it is a good one. But for the sake of
completeness: you could also use the observer pattern here.
Some articles about it.
