An Introductory Book to Business Intelligence

Business intelligence (BI) has been a hot concept. I have been wondering what it is exactly. Now I get a satisfactory answer from the book Business Intelligence: Making Decisions through Data Analytics. This book gives a thorough and systematic introduction to BI and its tools. Basically, BI and its tools are derived from the following four areas: statistics and econometrics, operations research, artificial intelligence, and database technologies. This book successfully connects what I have grasped to BI.

I guess it would be a good idea to start to explore BI from this book.
