It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to 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. ## More resources: * [Website](http://www.doctrine-project.org) * [Documentation](http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/index.html) * [Issue Tracker](http://www.doctrine-project.org/jira/browse/DDC) * [Downloads](http://github.com/doctrine/doctrine2/downloads) [Master image]: https://travis-ci.org/doctrine/doctrine2.svg?branch=master [Master]: https://travis-ci.org/doctrine/doctrine2 [Master coverage image]: https://coveralls.io/repos/doctrine/doctrine2/badge.png?branch=master [Master coverage]: https://coveralls.io/r/doctrine/doctrine2?branch=master [2.4 image]: https://travis-ci.org/doctrine/doctrine2.svg?branch=2.4 [2.4]: https://github.com/doctrine/doctrine2/tree/2.4 [2.3 image]: https://travis-ci.org/doctrine/doctrine2.svg?branch=2.3 [2.3]: https://github.com/doctrine/doctrine2/tree/2.3 [2.2 image]: https://travis-ci.org/doctrine/doctrine2.svg?branch=2.2 [2.2]: https://github.com/doctrine/doctrine2/tree/2.2 [2.1 image]: https://travis-ci.org/doctrine/doctrine2.svg?branch=2.1.x [2.1]: https://github.com/doctrine/doctrine2/tree/2.1.x
