Doctrine ORM
Doctrine ORM is an object-relational mapper (orm) for php 5.4+ (starting with 2.6 version php 7.1+). The Doctrine project is a collection of open source libraries and tools for dealing with database abstraction layer (dbal) and Object-Relational Mapping written in PHP. One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (dql).
Differences between Doctrine 1.2 and Doctrine 2.0.0
- Doctrine 1.2 implements ActiveRecord design while Doctrine 2.0.0 implements DataMapper design
- Doctrine 2.0.0 requires PHP 5.3 or newer and uses its benefits like namespaces.
