What are the viable database abstraction layers for Python

Question

I\'m starting to get involved in an open source project Gramps which is exploring switching their backend from BSDDB to a relational database. Either SQLite or MySQL we have

Answer 1

I think that CouchDB would be best choice for such project as Gramps.

Useful CouchDB features for Gramps:

• No schema, no migrations.

• Support for storing files directly to database, for example family photos, etc.: http://guide.couchdb.org/draft/api.html#attachments

• Ubuntu supports CouchDB via desktop-couch and it is integrated with Ubuntu One for easy sharing or backuping: http://www.freedesktop.org/wiki/Specifications/desktopcouch

• You can easily replicate couchdb databases, join them to one big database, etc...

• couchDB is very flexible.
