I know David Gassner’s, the author of the “Adobe Flash Builder 4 and Flex 4 Bible”, teaching approach from his famous Lynda.com courses. He is a great tutor. When I got his new book for review I was very curious if he was as a great book author as an on-line learning presenter. And yes, his new book “Adobe Flash Builder 4 and Flex 4 Bible” is a great resource for every Flex developer. This book covers nearly every aspect of creating Flex application and using it with conjunction with server side technologies like SOAP-Based Web Services, BlazeDS and Java, ColdFusion or PHP. The book consists of five parts: Flex Fundamentials, Designing Flex Applications, Working with Data, Integrating Flex Applications with Application Servers and some misteriously named Additional Subjects including deploying applications with AIR. Each part contains many topics. Most chapters are accompanied by sample Flex applications and other source code that can be downloaded from the Wiley.com site.
If you are a junior Flex developer you should read the book from the beginning. If you are extending your skills from Flex 3 to Flex 4 and Flash Builder 4, you may read chapters in any order. Either way the book provides you with valuable and precise information.
The book is very thick. On one hand this is it’s biggest weakness, on the other hand, the material gathered there constituting its size, is very well structured and presented. The book is optimized and organized. I could find any information I needed in just a few seconds skimming pages belonged to a particular chapter. I must say I admire David Gassner for that.
I use this book as a quick off-line reference resource. For more sophisticated topics I use it as a starting point in my research. The book helped me to move from Flex 3 to Flex 4 and let me make a better use either of new Flash Builder 4 functionality and Flex SDK features.
If there were only one book you could choose about Flash Builder 4 and Flex 4 (on beginner to intermediate level), one complete reference covering almost every Flex related aspect, you should pick this book. There is no other choice. Trust me
