This sounds great, but please quantify.
Based upon what specific & quantifiable metrics
can anyone conclude that any specific index is
"properly aligned with the underlying table and
that its entries are not sparse."
>Clustering factor ratios are just one of several indicators
At what values does the clustering factor ratio turn from a goodness indicator to a badness indicator. What is YOUR formula for computing the clustering factor? Is a high clustering factor ratio a good or bad indicator? What are some of the other unspecified indicators and how are they calculated or obtained? Received on Sun May 09 2004 - 13:13:46 CDT
