I'm getting familiar with Toplink (which is similar to Hibernate)
but that effort is not Xastir-related.

Agreed.

We need full-featured databases like MySQL/PostgreSQL, plus lighter
databases like Berkely-DB or SQLite to cover the various types of
platforms we're interested in.  Having a software layer that
insulates us from that end of things would be a big plus.

What I'm finding with web searches is that the term "Data
Persistence" is mostly used in the Java world.  I'm not sure Java is
the best language to use across all the classes of device that we're
interested in, but then again, it might be.
