Doctrine ORM is an object-relational mapper (ORM) for PHP which 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.
