Currently, many databases exist.

* SQL based: MySQL, PostgresSQL, SQLite, etc..
* KVS: Cassandra, HBase, Kumofs, Redis, etc...
* Document Oriented: MongoDB, CouchDB, etc...

I think next Database API should support these types.
AFAIK, DDBI supports only SQL based interface.

In Ruby, Rails 3 has Arel.
Arel seems to be a good query abstraction.

Arel's concept may help you :)
