refactoring models

Chris Habgood wrote in post #974022:

I have the rails antipatterns book and I am doing some refactoring. Is
there a big resource difference between a rails model backed with a db
and just a regular model other than the metaprogramming methods being
defined for the rails model/table

Resource difference? You mean in terms of performance or something
else? I'm not sure I get what you're asking...
