Welcome to the DoveSoft Introduction to Adobe Flex which is an application development platform used to build Rich Internet Applications (RIAs). Flex applications are Web-based, but they provide levels of interactivity and rich media experiences that make them seem more like computer desktop programs than traditional Web applications. Flex is the ideal technology to use when you want to create complex data visualisation, performance dashboards, multimedia experiences, and countless other interactive applications. RIAs have raised the bar for Web applications, and Flex is leading the way. Adobe Flex applications are created using the various pieces of the Adobe Flex product line, which includes the following:- ■ The Flex Software Developers Kit (SDK) ■ Flex Builder One major difference between the SDK and Flex Builder is that the SDK is free, while Flex Builder is available only through a licence that you may purchase from Adobe Systems. This link also demonstrates many  solutions from Adobe and also includes excellent training and documentation resources. This DoveSoft site demonstrates some of our Flex examples including data grids, a vehicle expenses calculator, interactive charts demonstration, and the accordion text navigation component. The left pane of this page includes an RSS feed from the Adobe Flex Development Centre. The site has been made with Xara Xtreme 5. Our Xtreme HTML page includes a Flex component to create rich text HTML for use in a placeholder, and tips on creating favicons.                               Site made with Xara Web Designer 7 Premium
