Re: XMI reality check

[Philip Goatly <philip.goatly@bolero.net>]

Bob,
I have tried the IBM toolkit below, and it falls over with any decent size
model - i.e it runs out of virtual memory after about 45 mins ( Yes I have
416 megabytes on my PC unused !!). This did not fill me with great
confidence I am afraid, since I can process the same model - every class- to
produce o/p to a database from which I can construct many different
artifacts. The whole process takes 5 minutes with no memory problems. I am
not using the fastest language available (VBA) but of course IBM is using
Java on the PC - not I think a very good combination, if one wants
efficiency.

Still if the only tool you have is a hammer, the whole world looks like a
nail

Cheers, Phil
