How Rich Internet Apps Work

摘要

Rich internet applications leverage the power of end-user devices by introducing to browsers features commonly found in the graphical user interfaces of desktop applications. Better RIA development tools, whether based on Ajax, Java, Flash, or a hybrid model, support creation of applications that can function on a range of browsers and devices, from smart-phones to the desktop. They also allow for flexible, fast, and efficient access to organizational resources, whether delivered internally or via a software-as-a-service model in the cloud. Capabilities that are often delivered through R!As include information mash-ups, high-volume data search and analysis, planning, visualization through maps and other content, and training. Beyond the improved user experience and ease of distribution, RIAs are getting easier to develop as well, thanks to hooks into robust technical libraries, declarative programming techniques, form creation abilities, Web services, and other capabilities.
