Well in my experience of MVC you tend to package and pass an object full of information to the view module for displaying. I believe Dawn is saying when this data is reconstructed that package has a data model. One might disagree with this, but even if one ride's with that assumption, I can currently see no theoretical reason that the reconstruction cannot be into an RM 1NF format, even if it is nonsensical to do so in terms of processing.

Similarly I could send a map of (person, email) or a vector of person objects, each containing email attributes. Exactly the same information, the first corresponding to 1NF and the second to non-NF. I don't see how any UML specification precludes this. Received on Tue Feb 14 2006 - 09:57:27 CST
