That's precisely what a model is NOT! A model highlights certain features
of the thing modeled precisely because
it omits some of the detail.
If you were building a 12 foot model of the titanic, you wouldn't expect all the toilets to flush! And it's the smae way in modeling SW or databases, or anything. The model isn't the thing itself, and it doesn't model everything about it.
Otherwise the model would be a s hard to build as the thing it modeled. Received on Wed May 05 2004 - 04:53:51 CEST
