Re: EOPrototype help

While I would love to get that book, I don't think it's possible at 
this time...
I also can't find anything on either of those sites.  Lot's of stuff 
for changing the connection dictionary and modifying just about 
everything else.
Nothing for prototypes though (not yet anyway, still looking).

Maybe I just don't understand what the separate framework is for, but 
it seems a bit much for what were doing.  The database structure will 
be exactly the same no matter what DBMS is used.
All I need is a separate prototype for each database, using the same 
eomodel file.  That is what the extra framework is for right?
But why create a completely new framework when all I need to do is 
replace the EOJDBCPrototypes when the model is loaded.

It just seems easier and less prone to programming and packaging error 
to me.  Maybe one plist file for each different database that is 
packaged with my existing model framework or just do it right in the 
code.
