Query: A beginner book....

If you you are just starting out then this book may work for you. With regard to using the text as a reference or just to brush up on your Access then it failed miserably. Because the practice chapters build on each other, you practically have to work through all of the previous chapters to build up the database, thus if you skip chapters and work on your topic of interests, the database failed because of missing data that was supposedly created during the previous chapters, which is pretty much useless as as brush up text.
