No defect? No deficiency? No limitation, if you find that more "charming"? I have no use for pointless extensions. I can certainly think of limitations--like the lack of support for schema evolution or for multiple application views--that would warrant considerable extension. But extension for extension sake? No thank you.

Given that Halpin formalized and extended Nijssen's text based methods with graphical methods, I fail to see a need to extend them back to text. (I am not a big fan of graphical analysis and pretty pictures, but I have to credit Halpin for making ORM and NIAM available in relatively inexpensive tools and for popularizing them.)

That's nice. I suppose that's why you cite your friend Halpin and ignore the real source of his methods.

I note that mathematics and logic have exactly as much use for charm as internal combustion engines have for foreskins, and "little" is not an apt adjective for me--not at all. Sophistry relies on charm, but thus far, sophistry has contributed not one thing to the field.

If your work has substance, you will be able to describe at least one advance it makes succinctly and without any hand-wavy bullshit or ad hominem sales pitches. You already know what I concluded from what you have written so far. Received on Mon Sep 28 2009 - 05:40:23 CEST
