DM: question

[Crispin, Hiroko M. (hmcr)]

Hello,

Has anyone used/evaluated See5 by RULEQUEST? If so, I am interested in
your opinion about:
             1. ease of use
             2. accuracy of the results
             3. if you think this is a good tool for modeling:
                        1. customer retention
                        2. new service acceptance
                        3. fraud detection.
             5. Can it process a large amount of data (about 500M) in 
a
relatively 
                 short amount of time.
             4. other

Also, any thoughts/advice on the good/effective tools to do 3.1, 3.2,
3.3 will be appreciated.

Thank you.
