Doctrine ORM

The ORM is built on top of a powerful database abstraction layer called DBAL.

The developer can write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL.

This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
