I had the opportunity to spend a day in a seminar with Ralph Kimball. If you don’t know who that is, he is a guru of data warehousing. If you’re involved in data warehouses, I hope you are at least familiar with his work. Currently in the industry there are two primary, competing warehousing methodologies, i.e. practically religions to some, Kimball vs. Inmon. I think that’s kind of silly. A methodology is like a hammer or a drill; choose the best one for the job. If I absolutely have to pick, I’m in the Kimball camp.
