Domain Model ORM Adapters

o I’ve had a series of articles that focus on domain model programming methodologies and most of my examples have demonstrated implementations using the Doctrine ORM (Object Relational Mapper). Given the nature of domain model programming I’ve held to the assertion that models built using this method are truly ORM agnostic and it should be effortless to swap out Doctrine for the ORM of your choice. Well I like to put my money where my mouth is by showing how easily this has been done by showing off adapters that I have written, one for Doctrine, and the other for Zend_Db. The beauty of this system is that both support the same ORM agnostic query syntax demonstrated in my recent post about creating complex sql queries using associative arrays. This means that no modifications are necessary in the models, controllers or views when switching ORMs. Developer’s utopia.
