Your application's model should be a tool, not a chore.sfEzModel is an annotations-configured ORM library for Symfony: an Open Source Web framework written in PHP.
Guiding principles make a project successful.Adopt one database platform, and utilize it well. sfEzModel is not database agnostic. I have chosen MySQL because it works well, I know it well, and it and PHP were undoubtedly separated at birth.
Configuration belongs in the code, not in YAML and not in XML. With sfEzModel, you configure your persistence model with php-doc annotations in a style inspired by the Java Persistence API.
A growing data model should not harm an application's efficiency. Generate less code, implement more functionality in the base classes, and let the framework do the caching.
Two choices: terminate on exception or log a warning. And when configured for termination, do so by throwing a logically named exception back to the Controller: zero thread death inside the model layer.
Absolute normalization. If your model isn't normalized, you're trying too hard.
