Yes, thanks.  It looks like this will be a very useful tool in my future 
projects.  I know very little about SQL right now (except for a 
roughly-how-it-works and that it is a networked database), so I've got quite 
a bit of work to do in that respect.  It doesn't seem really well-suited to 
geometry, but it looks like a "front end" would allow you to more easily 
manipulate objects.  What about binary data?  Can you store a float in the 
table without storing it as a string (and could you match on the binary 

It seems that the real trick here is going to be getting a modeling or 
drafting (or both) package to "play nice" with the sql (maybe via vba, but 
I'd rather steer clear of that route unless it is unavoidable).

Are there any database servers that allow data to be recalculated based on 
other updated data, or do these relationships have to be handled by an 
external program (maybe a change to one field would initiate a call to an 
external process?)
