Hidden Makrov Model sounds great from the limited bit I've read on it. I'm still using flat files here. I never did have the time to explore converting to a proper db. I've got the berkeley db modules installed, but not the full package. I'm on windows. In order for this to work, I'd need to install the Berkeley DB software itself right? ( http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html) Does version 11gR2 work with this?
