I too will recommend Kimball.

I will also add that I have been pulled into numerous DW projects as a consultant that were near or complete failures, in an effort to get them back on track or be successful. I have heard the same from others and from articles I have read in trade journals. Most companies that attempt data warehousing think they can just slap something together and it is a disaster. The best way to have a successful DW project is to engage with a consulting firm that has significant experience in doing it - there are SOOO many ways things can go south!! Note I say firm because data warehousing encompasses multiple disciplines and I don't believe there is a single person out there that can provide all the services you would need to make the project a success.
