Implement the database abstraction layer (DBAL) #32

Closed shiroyuki closed 10 years ago

shiroyuki commented 11 years ago

This is to implement the database abstraction layer to relieve MongoDB as the default database of choice. This also the ORM platform-agnostic.

DBAL will open the possibility of supporting all kinds of data storages, including:

Riak
Amazon Dynamo
MySQL / MariaDB
Google App Engine's Datastore (bridge)
LevelDB via py-leveldb
Redis

Checkpoints:

[x] Rewrite the use of low-level APIs to use the Driver-based architecture.
[x] Rewrite the query mechanism to where Criteria is sort of backend-agnostic.
[x] Update Criteria to support joining and completely backend-agnostic. (Deferred to #30)
