DW/BI books

What are your favourite DW/BI books and why.

Just wanted to see if there are any interesting books out there that I haven't come across.

I have two favourites:

- The Datawarehouse Toolkit 2nd Ed (Ralph Kimball, 2002)
Duh.

- A Manager's Guide to Data Warehousing (Laura Reeves 2009)
The first two chapters deal with "selling" the data warehouse and managing stakeholders. Most books on DW/BI fail to really deal with the "political" side of datawarehousing, despite the fact that from my experience it is behind many of the common causes of project failure. Reeves' writing style is very dry (at times you'll feel like you are sucking sand), but her content is excellent. I regularly refer to her first three chapters whenever writing or presenting for stakeholders.

RK's new book (The Kimball Group Reader) is entertaining reading. I haven't yet found it useful for any specific problem I'm facing but that could change.

I generally regard most "vendor-specific" DW books with contempt. To be fair I haven't read them all, but the specific tools and platforms used in a DW have a negligible impact on the success of the project. Good DWs come from good DW design and implementation, which comes from thorough and relevant analysis combined with adherence to design principles. I'm not saying all platform/product books are completely useless - they can show you which command to type or which button to press in a given situation. But they are typically worthless in regard to overall project design.
