If we can use postGIS across most/all platforms it'll save us from
having to do a lot of inherent GIS functions. That said, MySQL and
SQLite can also do a lot of the lifting for us. Access, believe it or
not, has been shimmed with some form of a spatial-awareness cloak. I'll
look into the resources needed to support that.
I'm still of two minds about java. I've got a couple of active projects
under me (but I'm not actively coding on them) that are java-based. We
see irritating little gotcha's with java all the time, though, and I
worry about that. Still, the security model is real good, and something
to consider for us.

I'm getting familiar with Toplink (which is similar to Hibernate)
but that effort is not Xastir-related.
I do a lot of coding on various PHP, Java, and MS Access front ends over
MySQL, Oracle, and Postgresql. Generating objects from a database
schema with tools like hibernate is much easier to do and maintain
than doing it by hand.
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.
I'm in the process of hacking a PHP 5 object persistence layer
supporting CRUD into Druid, but the objects representing the tables are
themselves connecting to the database, rather than hibernate's more
abstract (and better for plugging in different back ends) framework.
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.
