Introduction to Rich Internet Applications, Flex, AIR

Rich Internet Applications (RIAs) are applications delivered via the web that have rich functionality similar to desktop applications. RIAs aim to provide a more seamless user experience than traditional client-server applications by allowing for greater interactivity, improved graphics, and reduced page loading times. Flex is a software development kit used to create RIAs using Adobe Flash that can run on both the web using Flash Player and on desktops using Adobe Integrated Runtime (AIR).
