On a recommendation, I picked up this book by Ralph Kimball. I remember it coming out years ago and I saw a speech by one of the co-authors, Margy Ross. She was great and I thought DW would be great. Then I got sidetracked into the OLTP world with a financial startup and let things go.
Years later it seems that warehousing is slightly more than a niche market, but since I'm heading to Seattle for the BI Conference, I thought I should learn a few things.
Chapter 1 is lots of terminology and trying to get you in the DW frame of mind. I'm not sure I'm completely sure of what it all means, but I'm plodding through it, trying not to go too fast and make sure I learn some things.
