In this excerpt from the Overview of Drupal 7, Angie Byron, talks about the Database API in Drupal 7. This was a round table discussion with other Lullabots on the line who ask and answer questions, in addition to Angie's presentation. This lays a good foundation for how the database system works in Drupal and sets you up for the hands-on tutorials that follow.
