Dimensional Modeling in Business intelligence Environment, an IBM RedBook.
I came across this book some 3 months back, IBM RedBook series never cease to amaze me for the quality and clarity of their publications. In fact, back in 1999-2000, REALSOFT (where i am a co-founder), was awarded our first Data warehouse solution for the ministry of national economy in Oman social and economics indicators database. Guess what, IBM RedBook came to our rescue with their excellent data modeling techniques for data warehouse (http://www.redbooks.ibm.com/abstracts/sg242238.html?Open) , it was THEE book that laid down the ground for our understanding of data warehousing concepts and design.
