An approach I've seen before is to encode things into a department id. All North American departments start with 1,
etc.The rollups are then done by truncating the id down to the granularity required. At least this was the approach my
previousemployer took. They were more interested in particular customers, so the encoding was based on that. This was
ona relatively small scale basis (~500 employees and few enough customers to count by hand). I'm not sure how well that
wouldscale. It definitely takes some planning and forethought.
