Query: Poor book for the exam (70-029)

I wrote the exam, using this book as a primary guide, and failed.The exam was a shock, used language I had never heard of before (e.g. 'surrogate primary keys'), and the questions were of a practical, 'exercise' nature.Without use of practice tests, this book is dismally insufficient.Make sure you know what 'OLTP' and 'DECISION-SUPPORT' mean. Perhaps I'm an ignoramus, but I don't remember these terms being highlighted in the book.jp
