Well, I'm project leader (in name, not much else) of MaVerick, which is writing an open-source MV database (written in Java, actually :-) Go to www.maverick-dbms.org for that.
There's a version called jBASE (go to www.jbase.com), IBM have the U2 databases UniVerse and UniData, and there's "the original", now called D3 by RainingData but used to be Pick by Pick Systems.
I'd say go to IBM, download the Personal Edition of UniVerse, and play with it, but that's my bias because that's the version I know and understand.
Apart from D3, all the others are available as a freebie download, although only MaVerick is Free, the others aren't licenced for commercial use.
I've added comp.databases.pick to the cross-post - you might well need some help to get started and you'll find plenty of help there
This is the link for UniVerse Personal Edition - https://www-927.ibm.com/software/data/u2/support/u2techconnect/uv10pe.asp
