PDO
DB support as contribute: is it a good idea?
Abstract
Drupal 6.0 is revamped with Schema API, so what's next for Drupal 7.x? PDO for sure! With this powerful data-access abstraction layer, workload will much reduced for DB abstraction layer designers and developers, and finally benefit our contribute developers and end users.
By the way, together with the decision of Drupal 7.x + PDO, there is also some voice about moving PostgreSQL (and so other potential databases support, e.g. Oracle, DB2, MSSQL, etc) support away from core, but contribute; on the other hand, add official SQLite support into Drupal core, together with MySQL.
Is this really a good idea? Or even if it is possible? As an existing Drupal + PostgreSQL users, what will this affect your daily work? As a potential customer of Drupal + Oracle/DB2/MSSQL/etc, is this a good new for you, or just an evil? I would like to provide some brief idea for you within this article.
