Doctrine 2 vs MariaDB: What are the differences?
Developers describe Doctrine 2 as "An object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects". Doctrine 2 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. On the other hand, MariaDB is detailed as "An enhanced, drop-in replacement for MySQL". Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry. MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
Doctrine 2 can be classified as a tool in the "Object Relational Mapper (ORM)" category, while MariaDB is grouped under "Databases".
"Great abstraction, easy to use, good docs" is the top reason why over 9 developers like Doctrine 2, while over 150 developers mention "Drop-in mysql replacement" as the leading cause for choosing MariaDB.
MariaDB is an open source tool with 2.82K GitHub stars and 864 GitHub forks. Here's a link to MariaDB's open source repository on GitHub.
According to the StackShare community, MariaDB has a broader approval, being mentioned in 496 company stacks & 461 developers stacks; compared to Doctrine 2, which is listed in 35 company stacks and 12 developer stacks.
