So I am trying to understand the difference. Suppose I have an MVC web app. Suppose I add some database triggers so that when some data is entered other things happen. Maybe I flag an invoice to be printed and the trigger notifies a waiting program which processes the invoice data and sends it to the printer. Now, from the perspective of any single request, the application is MVC-centric. However, from the perspective of the application structure as a whole it's not, because model operations trigger other operations which can have other effects beyond the immediate knowledge of the model. Is that kind of what you are talking about? MVC with a sort of events backplane?
