Thanks Adam!

UniObjects for Java.  (Yes, UniData and its near-twin UniVerse are now owned
by IBM.)  I have objects such as UniFile and UniRecord and UniDynamicArray
to work with.  UniData (my version at least) does not have a JDBC driver and
it does not speak SQL.  (Even if it did, "normalizing" the data rather
defeats the purpose of having a multi-valued database. :)   So all the
existing ORM tools are out-- IBM sells RedBack, but it's low 5-digits and
I'm not sure it's justified.

It took me a while to realize that the ORM part is where I'm stuck.  This is
a great link, thanks!
