understanding MVC

Hello,

I'm playing with BSP since 1 week and have problems understanding the model and data binding part of MVC. Is there a tutorial out there?

Generating simple BSP with event handlers, generating views & controllers, using htmlb and doing the bookshop examples was no problem.

But understanding how to use the class CL_BSP_MODEL, or the structure behind the itmvc2 example is a problem.

Where to find documentation, examples etc. ?

Thank you for any help!
