Subj:   Re: Teradata Warehouse Miner recommendation
 
From:   Jim Downey

I did a 30 day evaluation about a year ago and barely scratched the surface.

I have not done a lot of statistics and was overwhelmed with much of the capability. I enlisted help from actuaries but their experience with SAS made them unwilling to look at a newer, less mature tool in any detail. I expected the tool to do the data mining but YOU do the data mining, the tool just helps with the grunt work.

I liked that the tool generated SQL that ran on Teradata. (as opposed to extracting and doing analysis) it allows you to capture the SQL which made it nice to store and repeat queries. The on line manual is great. Especially for a novice with statistics.

I didn't like that you had to denormalize the data to get some of the algorithms to work. In some cases, this was via views which was OK. I suspect that how you denormalize the data as input to the tool impacts the analysis done by the tool. Again experience that I didn't have pays off.

We played around with the concept of marrying Teradata Miner, Angoss and MSI and what it could deliver.

I would like to give it more time but our power users have another tool.
