Data Mining Worst Practices

This Way Failure Lies is a Database-neutral article in DB2 Magazine on how NOT to approach a Data Mining project. Many good tips in this area which is still a bit of black magic.

And by the way, any DW/BI people should look into the DB2 Business Intelligence Certification from IBM. It's 2 tests , one with generic DW concepts, and the entry level DB2 test. They are fairly easy for someone with experience, and a good base that will open doors in some places. The Study guide to the BI test (free) is a very good introduction to data warehousing, better than just about any non-free book I have seen.
