Re: Oracle DK2000 Three-tier client/server?

Oracle D2K version 2 is supposed to allow JAVA application modules separate from the Oracle RDBMS. Current verions are not 3-Tier.

The best 3-Tier product I have seen is Forte, but it's very expensive.

JAVA and the inter/intra-net has changed much of how future development /deployment paradigms will look architecturally.

There are several interesting decisions to be made for current application developers. D2K may be of interest to you or may not depending on your goals and how well you can predict the future.
