I don't think that the native APIs have much in common and seen
from the cross-database portability ODBC is pretty hard to beat, IMHO.
But, I'm biased :-)
What one might try is implementing a different technique of
accessing databases altogether: a class based view of things,
where tables become objects and queries are built from sets
of select-objects, join-objects, etc. These would enable a
much cleaner (though less rich) interface to all sorts of
databases - even non-SQL ones.
