I am in the process of upgrading from Doctrine 1.1.4 to Doctrine 2.0.6 in my Zend application.
Currently, I am working on mapping the associations between entities. In Doctrine 2's Documentation it says 'relationships maybe bidirectional or unidirectional. I am confused as to what these terms mean within the given context.
How do I determine if a relationship is unidirectional or bidirectional?
Appreciate the help.
