Summary: Many Flex books cover the basics—this book does something different, and goes far further. The authors, leading Flash platform developers at Almer/Blank, working with Adobe User Group communities, are the creators of the Rich Media Exchange (RMX), a social media network for Adobe developers. In covering just how the RMX was built, this book contains all the knowledge you need to build similar large-scale Rich Internet Applications with Adobe Flex. From the inception of the idea through to deployment, the authors show the techniques needed to plan and build advanced applications. You'll learn how to use forms, styles, validators, video, sound analysis, and framework caching, ensuring you make the most of the new features introduced in Flex 3. Powerful applications require solid back ends. This book shows how to hook up a Flex application to PHP back-end systems such as Drupal and OpenAds. You'll learn how various parts of the RMX were built, including the blogs, event calendar, jobs board, and advertising system—elements that come together to really showcase the power of Flex.
