No, he can only interact by going through the Controller and the Model > I was wondering > however, is the "MVC" that I've read about different to the 3 tier > architecture or is it a 3 tier system within a 3 tier system?

I think the MVC concept has pretty much superseded 3-tier for web applications. Using http://en.wikipedia.org/wiki/Multitier_architecture as a reference. I would say that approximately the Data tier maps to the database driver (MySQL or whatever). In Rails the Logic tier is further divided into the Model, which handles business logic and the Controller which handles requests from the user and makes data available for the View. The Presentation layer more or less maps to the View. Though possibly it would be better to show the controller riding the dividing line between the presentation layer and the logic tier. No doubt others will have different views. To be honest I don't think it matters much. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
