RE: MVC

Hi,
This started because I wanted to create a very small project in Java to put 
together what I'm learning about classes and such as I go along. I was thinking 
that if I created a calculator program that a small project like that wouldn't 
get in the way of learning too much. The model would be all of the methods that 
do the math. The controller would be that part that figures out which math 
methods to call. The view would be what the person who runs the application 
sees. At first, it would be a command line interface. Later, if I've done it 
correctly, it would maybe be a user interface built with SWT. As I catch onto 
arrays, I could build a method that, let's say, adds as many numbers as are in 
the array. I'm reaching for examples here. 

Jim

Thanks.

Jim

This is the version of MVC most commonly associated with the web. MVC is not 
always under such restrictions. For example, sometimes,
it's necessary to move where you maintain state, simply because of definitions 
you've laid out that state the view can't speak to
the model directly, even though other definitions imply a lack of state being 
maintained anywhere but in the model.

Frankly, I'm not a huge fan of MVC. I find it impractical, very limiting, and 
very rigid. I sort of liken it to the waterfall
development methodology of software engineering. I tend to be more of an 
agile/star model guy, which means that I also really like
things like software busses.

Again though, different strokes for different folks.

Take care,
Sina

a little bit different...
1. the model is formed from classes that assembles your domain and your 
business logic.
Let say that there you will find classes like person, account, or something 
similar.
But the model does not power lifting, it simply offer services.
2. The controller takes al user information/events from the view and uses the 
services ofered by the model to make necesary changes.
3. View pass to the controller al  user information/events and then query the 
model about its state changes to reflect them on the
view.
Simply:
the user does something, the view announce the controller that the user has 
done something.
The controler, makes necesary calls to the model to cary out the needed actions.
The view sees if there are model changes and display them.

        Hi,

        Is this how Model View Controller works?

         

        1. You have something on the back end, the model,  that does all the 
heavy lifting.

        2. On top of that, you have the controller, which sits between the user 
and the model that calls the methods of the model.

        3. The view simply passes information from the user to the controller 
which the controller interprets for the model.

         

        Thanks.
