What is the difference between MVC & MVP MVC

Controller responsible for determining which view is displayed in response to any action.

The view does not directly bind to the model. The view usually will not have any logic in the

code behind. MVP

Presenter contains the UI business logic for the view.

All actions from the view delegate to the presenter.

Tends to be a very natural pattern for achieving separated presentation in ASP.NET Web Forms.

What is the DRY Principle? It means “Don’t Repeat Yourself”, but it isn’t

necessarily talking about the Copy/Paste Code Smell… that is better described by the “Once and Only Once” (OAOO) principle.

An example of something really DRY is XSLT… where knowledge is not repeated.

“The DRY code philosophy is stated as ‘Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.’” --Wikipedia

What is the PRG Pattern? “…instead of returning an HTML page

directly, the POST operation returns a redirection command… instructing the browser to load a different page using an HTTP GET request. The result page can then safely be bookmarked or reloaded without unexpected side effects.” --Wikipedia
