It's beautiful in its simplicity, as Terence Parr notes:
For the "MVC" of a web app, I make a direct analogy with the Smalltalk notion of MVC. The model is any of the logic or the database or any of the data itself. The view is simply how you lay the data out, how it is displayed. If you want a subset of some data, for example, my opinion is that is a responsibility of the model. The model knows how to make a subset. You should not be asking your graphics designer to filter a list according to age or some other criteria.
The controller in a web app is a bit more complicated, because it has two parts. The first part is the web server (such as a servlet container) that maps incoming HTTP URL requests to a particular handler for that request. The second part is those handlers themselves, which are in fact often called "controllers." So the C in a web app MVC includes both the web server "overlord" that routes requests to handlers and the logic of those handlers themselves, which pull the data from the database a
