The two Python solutions that come to mind are the pickle and cPickle
modules, which just allow you to save and restore Python objects, and
ZODB, a full-fledged object database from Digital Creations:

If you are willing to compare these with Perl or Java approaches, I'd
be interested to hear what you think.
