One of the more epic changes to Drupal 7 is a new database layer that's based upon PHP's Data Object (PDO) library. Larry Garfield, being a fan of Star Trek, gave it the nickname of "Database, The Next Generation" (DBTNG) and collaborated heavily with chx, Barry Jaspan and Damien Tournoud on it.
In this podcast, Larry explains some of the new features and what they mean for Drupal developers.
