Hi Nelson,

if your boss is thinking that you're a magician, tell him that magicians 
need the opportunity to buy magic components. I don't think that a 
GRASS-RIM combination is the best tool available to make a user-friendly 
GIS database for this kind of application. Over the last few months we 
have been experimenting with MapInfo, which is not too expensive (we 
payed around $1500), runs very nice on a PC under Windows and does all 
the magic tricks you're asking with a simple set of dBase files and 
imported DXF-layers. It performs all kinds of queries you can imagine on 
your database, and even has some minor GIS-analysis capabilities; just 
fine for people like your boss, I'd imagine. If you're interested, mail 
me.

Adios,

Philip Verhagen
