I don't dismiss, I demonstrate with examples :) Take from the results what you will.

It isn't a matter of how well the underlying data structure is hidden. It is a matter of what the underlying data structure will allow one to represent in a general/flexible/systematic manner.

Have a conversation with Bob Badour or see Date's books.

Exactly what it says :)

I could be wrong, so please demonstate the following in Prolog:

like (john, mary).
hate (john, bob)
opposite (like, hate)

:)

>> Some of these cannot be realized in a static example but rather by observing how a methodology's steps to implement the next set of requirements are affected. Consistency/systamaticness in meeting progressive requirements become more of an issue in AI type apps (ie an andriod) which would continually face changing requirements.

:) You are expecting a static requirement. My requirement is how to best meet dynamic requirements (ie like those of an andriod). Received on Sat Apr 29 2006 - 14:43:52 CDT
