NSTableView app design

Subject: NSTableView app design

Following Hillegas, I have questions about using NSTableView objects.

In both Hillegas' chapter on Helper Objects and Apple's online docs on using NSTableViews, methods are used to explicitly return the number of rows in a table and the value of an object in a specific column (as well as setting the value). In the following chapter on Bindings, none of these methods is called. An NSArrayController appears to handle those tasks. Do I have this correct? Does using the view's bindings obviate the need to call numberOfRowsInTableView:, &c.?

Also, if I understand correctly, a tableView object's data source is considered part of the app's controller, in M-V-C terms. Using bindings and key-value coding style accessors, the functionality that would've been handled by the controller is now accessed directly in/ from the model. Is this correct?

Thanks in advance!
Scott
