Doctrine in a PHP programming

Doctrine

Home page: www.doctrine-project.org. Current version: 1.0.2

Doctrine is a PHP ORM for PHP 5.2.3+ that sits on the top of a powerful PHP. One of its key features is the ability to optionally write database queries in an object oriented SQL-dialect called DQL inspired by Hibernates HQL. This provides web developers with a powerful alternative to SQL that maintains a maximum flexibility without requiring needless code duplication.

Doctrine requires PHP 5.2.3+. It doesn’t require any external libraries. For the database function call abstraction Doctrine uses PDO which comes bundled with the PHP official release that you get from www.php.net.
