This book is a survey of information systems, with helpful definitions and examples. However, the discussion of individual systems and technologies don't seem authoritative or perceptive of future trends. I don't think there should be more details necessarily, but the topics are sort of cobbled together without a strong context of how these technologies and systems will change.
If you were to just read the Wikipedia entries on software, business intelligence, and databases, for instance, you'd have a better working definitions of these ideas.
Make sure to buy the latest version of this book, because the terminology and topics covered will quickly become dated.
