Doctrine ORM is part of the Doctrine Project, which is the home to several PHP libraries primarily focused on database storage and object mapping. Doctrine ORM, an Object Relational Mapper (ORM), is one of the core projects, and sits on top of a powerful database abstraction layer (DBAL).
One of Doctrine ORM's key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), which provides developers with a powerful alternative to SQL that maintains flexibility without unnecessary code duplication.
Doctrine ORM has been downloaded more than 60 million times. You can learn more about Doctrine ORM on the project docs.
Doctrine ORM is available via Packagist.
