This groundbreaking book shows Flex developers exactly what's required to build production-quality Rich Internet Applications (RIAs) for the enterprise. Part of the popular Adobe Developer Library co-published by O'Reilly and Adobe, Enterprise Development with Flex goes well beyond Flex tutorials and product documentation to suggest best practices, compare frameworks and tools, and offer efficient techniques for developing enterprise RIAs.
