I would be interested on here some of your experiences on this?

I've built and made use of table hierarchies three levels deep and about twenty 
classification
types wide that I rolled up into separate update-able view.  However, I found 
the process of
cascading the updates to all three levels of each classification type using the 
"TID" rather
tedious.
