Summary: Use for competitive analysis of dB2
Review: This is one of the latest in a series of study guides that Sanders has put together for various dB2 certifications. As with his earlier books, a lot of its value is in the focus on what you need to know to pass an exam, in this case, the 703 exam. You will find an extensive question set at the end of each chapter, with answers later in the book. These question sets are indispensible for testing your knowledge understanding.But there is a second potential use of this book. It lets you concisely see various technical abilities of dB2. Useful if you are considering using dB2 or one of its competitors, like Oracle or Postgres or MySQL. For example, MySQL's most persuasive argument is that it is free. But it has limitations. No stored procedures [yet]. By contrast, Sanders describes these in dB2 in various chapters, and how they can reduce bandwidth in a client-server application, to cite only one instance. Another example of using this book to compare dB2 and MySQL might be the book's discussion of using foreign key constraints in dB2. Whereas currently in MySQL, foreign keys are not permitted. (Except in a very limited sense.) So with a little imagination, you can use this book as part of a competitive analysis of dB2. Perhaps not what Sanders or IBM fully intended. But the flexibility is useful.
