I have been using FileMaker Pro since version 5 and have read tons of books on the subject plus watched even more training videos. This book really took me by surprise.
Not being a novice user I anticipated that a lot of the book would review skills I already have. Instead, starting from the very first chapter, I began to understand those skills at a deeper level, which helped some more advanced topics become easier to tackle.
The author, Jesse Feiler, wrote a FileMaker Pro 8 book, which was good, but this book is so much better, it is hard to believe the same person wrote both! Whether you are new to FileMaker or are a hard core user, you will benefit from this book.
