I originally wanted to find out how to access the Doctrine 2's Entity Manager from within Entity Classes. But I saw another question Using EntityManager inside Doctrine 2.0 entities, and learnt that I should be using a service class. I wonder where should I put in a Zend Framework Application? Also is it also called a DAO (Data Access Object)? I am thinking of naming it DAO instead of Service as Service sounds alot like something for external sites to use (like Web Service)?
I am thinking something like Application_Models_DAO_User
?
