Whether you're a Flex 3 beginner or intermediate user, this book provides the necessary information to help you develop into an expert. Using a practical hands-on approach, it illustrates exactly how to create robust and scalable enterprise-grade rich Internet applications (RIAs).
The book is divided into three parts. The first part discusses the architectural and design aspects of Flex 3 application development. It explains the internals of a Flex 3 application and advocates a few best practices to fine-tune your application to ensure maximum performance. It includes tutorials on creating custom components, data binding, and creating AIR-powered desktop applications.
The second part concentrates on effectively integrating Flex 3 with server- and client-side technologies. Techniques for integration with Java and PHP are covered in detail, and content covering interaction with client-side technologies is also included. After reading the chapter on JavaScript integration, you will be ready to create applications that can use Ajax and Flex 3 together.
The third and final part of the book is a unique and eclectic mix of some advanced topics like mash-ups, collaborative applications, 3D rendering, highly interactive visualization, and audio and video streaming.
In summary, through reading this book, you will benefit from the wealth of information and years of experience the authors hold, and will then be ready to cruise with comfort in the world of Flex 3 application development on your own.

One of Flex's greatest assets is its approachability. A developer new to the platform can quickly get up to speed on the tools and APIs to create functional and visually appealing applications. Components, data, networking, charting, graphics, animation, and much more are available for use even by programmers who are just starting out with Flex. Much of Flex's power and robustness for novice users comes from its built-in use of its own capabilities. For example, someone starting out may not manually insert animations into his application, but the base Flex components come with some amount of animation built in so that even the simplest of applications demonstrates dynamic behavior, contributing to a rich expe- ence for the application's users. The Flex framework also provides many powerful features so that developers, when they are ready, can add more and more of these features to their applications. For example, states and transitions offer a rich way to declaratively describe different screens of an application and a- mate between those states. This is probably not something that beginning programmers would even think to ask for, but when they are ready for states and transitions, they have immediate access to these capabilities, which is far more convenient than if they had to build states and transitions themselves.
