It is factory since it is actually "Manufacturing" (Create) an object.

There's actually two kind of factory pattern defined by GoF:

Basically both of them tries to decouple the calling client from knowing the actual concrete implementation of the class/interface.

So this would be useful if you needed to account for the possibility that your model (in MVC) might change? Is there anything undesirable about creating a model in your application that is dynamic depending on the circumstances ? I'm guessing one downside is the added complexity of making sure that any permutations don't break your views or your controllers. – stonybrooklyn Jul 26 '17 at 16:10
