Need some explanation, please

In Yii docs right here in section 3. Controller http://www.yiiframework.com/doc/guide/1.1/en/basics.best-practices#controller it is stated, that:

may create model instances and manage their life cycles. For example, in a typical model update action, the controller may first create the model instance; then populate the model with the user input from $_POST; after saving the model successfully, the controller may redirect the user browser to the model detail page. Note that the actual implementation of saving a model should be located in the model instead of the controller.

I just don’t understand what it means:

Would much appreciate a good explanation!

Thanks.

it means that you make the call Model->save(), to save model data in the controller.

But the database call (e.g. insert/update query) to save model data to table should be there in the model. The controller should not interact with the database. If you are using Active Records, you need not worry about the save implementation, Yii takes care of it (save is implemented by CActiveRecord class)
