Hello there, I've been thinking to start a more complex project to learn how to work with MVC programming, but I don't really understand how it works, and haven't been very lucky so far on my research.
It would be really useful if someone could put some light in there

I've made a simple project building a calculator with this architecture, but I still can't abstract it to other scenarios.

In my model layer I had my calculator class, with just the 'calc' method which either added or substracted both operands, besides operands/op setters and result getter. Also it's builder.

The controller just had a method which would create an instance of a calculator and set the values of the operands and operation and return the result.

The View picked up the values of the textboxes once you either clicked +/- and sent them to the controller.

I don't know if what I did it's ok, nor how to, for instance, create an application to register people on a database. Where would the sql sentences be?

I know I'm really lost here, thanks for your time!

There are excellent tutorials and examples on MVC here on CodeProject; how about studying them ?

Hello,
For bellow

"I don't know if what I did it's ok, nor how to, for instance, create an application to register people on a database. Where would the sql sentences be?"

Your UI or interface must be in View
Model will contain Detabase related query , now controller will be bridge
in between them.

Here is some link for you hope this will help :)
