Similar caveat on my end: I have quite a bit of experience in the
relational database world but am still learning Core Data. (hence
my original question... so I'd appreciate enlightenment on where
I'm off-base in this reply.)
As in my last e-mail, there is positively nothing wrong with a) the
schema he proposed and, b) the number of instances.
The problem (as I'm gathering from the details that have emerged in
this thread) is his approach: He's creating everything first, then
establishing the relationships.
I appreciate your followup messages. I had tried a schema of similar
complexity (granted, it was a larger data set) and had fairly
unfavorable results under Tiger (re: memory usage and performance.)
It sounds like it might be worth another look under Leopard.
Thanks,
Phil
