I am trying to provide the two responses that I owe you, to complete the response to your post. But I am running into difficulty re the amount of detail required, and I need a quick clarification, please.

Since this thread is about the RM, I assume you mean, he then implements that thing that he considers the "natural" structure for data, in a RDBMS. (Otherwise the point does not apply.)

Could you please give an example of what one of those guys did, that you consider to be incorrect, and also your version of what that should be, if you corrected it, to what you think the "natural" structure is. Ie. they use it on everything, and you use it sparingly.
