>I agree. This point seems moot. If you argue that Get/Set are advantageous because you don't have to modify the middle tier to add a field, but you _do_ have to modifiy the field to practically use the get/Set methods (to add logic), this point defeats itself. IMHO Access/Assign is just as clean as Get/Set.

Erik,

No this does not argue against it self. The rules and logic can easily be data driven and that would still not require any changes to the middle tier class, only to its metadata.
