For Ruby/DBI (www.ruby-projects.org/dbi) I've written a simple storage system, that lets you store marshalled Ruby objects in an Oracle or PostgreSQL database (you can add more DBs; easy extensible) accessible through an arbitrary number of real database fields. See examples/persistence.rb. It's a (slow) alternative to Berkley-DBs, that only provide one access-key. But that is probably not what you are looking for.
