As is CC-BY-SA.  A collective work requires that "the Work is included
in its entirety in unmodified form along with one or more other
contributions".  To combine the databases into one database, you must
modify them.  To stick them next to each other on a hard drive
(including in a tarball, or in a zip file), you don't.
