Some time ago, while still at Microsoft, I was involved in a small business intelligence project. Many, many years ago, I was a database application developer, but times have changed. I had to get up to speed on how to build and use a data warehouse in a hurry. Fortunately, one of my best friends is a data warehouse developer for a large insurance company, and knew exactly which books to study. Recently, I was asked for book recommendations, so I’m passing along the books that Bob McClellan recommended to me.
