ObjectQuel is described as 'A domain-level query engine with integrated ORM capabilities, built on the Data Mapper pattern. ObjectQuel provides a purpose-built query language for expressing complex data relationships naturally, powered by CakePHP's database foundation under the hood' and is an app in the development category. There are 2 alternatives to ObjectQuel for Mac and Self-Hosted. The best ObjectQuel alternative is Eloquent, which is both free and Open Source.
Eloquent is a free & open-source application for research and study of God and His Word. It is developed specifically for Macintosh computers running Mac OS X.
The Doctrine Project is the home to several PHP libraries primarily focused on database storage and object mapping. The core projects are the Object Relational Mapper (ORM) and the Database Abstraction Layer (DBAL) it is built upon.
It seems the author meant Laravel's Eloquent, but this is a different kind of app.
