It defines MDD as when your application is code generated from a given definition file or interprits a data file. This seems to me that MS has finally picked up on the ideas expressed in the language TCL and are merely adding a user frindly gui to link them together.
Chris Sells did admit that MS did not invent MDD, just now they are tring to bring them to the fore.
MDD really is the practice of using meta-data where appropriate.
Delphi has had this for years in the seperation of a form into it’s dfm and pas components.
It has been possible to change a delphi dfm to add static components without touching the code.
