Hi Roger,
I have two thoughts on this: 1. I think normalization or denormalization has a wider scope than exchanging data. In NoSQL data stores, it is very common to denormalize data, because queries can run much faster (less joins). You exchange once (e.g., ETL), but you query many times. 2. Also, I would not be so sure that the association denormalized=flat, normalized=fat always holds. Actually, I would even have spontaneously made the opposite binding: consider flat data (that you could store in a relational table) that is, say, in third normal form (3NF), and you can then denormalize it by nesting pre-computed joins, i.e., making it fat. Just two quick thoughts. Does it make sense? Kind regards, Ghislain On Tue, Dec 2, 2014 at 11:30 AM, Costello, Roger L. <costello@mitre.org> wrote:
