Citat:Flex is a powerful, open source application framework that allows you to easily build mobile applications for iOS, Android™, and BlackBerry® Tablet OS devices, as well as traditional applications for browser and desktop using the same programming model, tool, and codebase. You can use the Flex SDK to create a wide range of highly interactive, expressive applications. For example, a data visualization application built in Flex can pull data from multiple back-end sources and display it visually. Business users can drill down into the data for deeper insight and even change the data and have it automatically updated on the back end. A product configuration application can help customers navigate the process of selecting or customizing products online. And a self-service application can guide customers through an address change or help employees complete an otherwise complicated multi-step benefits enrollment.
Apache Flex is comprised of a few different components. One component is the compiler which combines MXML (layout) documents with ActionScript files to output a SWF application.
You can then either publish the SWF file as a stand-alone application to be presented by the Adobe Flash Player in the browser, OR you can compile it with Adobe AIR to make native applications on Windows, MacOSX, Android, iOS, or BlackBerry platforms.
