What kind of data are you storing?  The ZODB is appropriate when you
have a lot of objects, will be modifying some unknown number of them,
and don't want to manage each individual change yourself; code can
just touch all the objects it likes, commit the current transaction,
and all the changes get written out.  But if explicitly writing out
the modified objects is fine -- perhaps you only change one at a time
-- then BSDDB3 is probably just as easy.
