Page 177 (Patterns of Enterprise Application Architecture - Martin Fowler) shows a nice diagram of how to design a Data Mapper... The Finders are happily accessed through the Registry, but I don't understand how the Update/Insert/Delete methods are accessed
on the Mapper. Does the UI instantiate the Data Mapper and then persist it (since the Mapper also contains the Identity Map)?
