RE: Record Length

Best example of "good" denormalization is a database used solely for
reporting. (Data Warehouse, if you'll excuse the buzzword.)  Transaction
processing works best with normalization.  Gotta agree that normalizing
the data (even if only on paper) is a good way to clarify the
relationships among the data elements.
