0 will have any meaning!
Oh yeah, and you should definitely put it on your resume somewhere. HR drones just love seeing it
thrown around as if you are the only one with THE definition of it!
RIA stands for Rich Internet Application. Although there is no formal definition with
which I am familiar, most people get the gist of its meaning without having to Google for it.
In short, the goal of an RIA is to create an application that is web based??”that is, it runs in
a web browser but looks, feels, and functions more like a typical fat-client application than a
???typical??? web site. Things like partial-page updates are taken for granted, and hence Ajax is
always involved in RIAs (although what form of Ajax is involved can vary; indeed you may not
find the XMLHttpRequest object, the prototypical Ajax solution, lurking about at all!). These
types of applications are always more user-friendly and better received by the user community
they service. In fact, your goal in building RIAs should be for users to say, ???I didn??™t even
know it was a webapp!???
Gmail (see Figure 1-12) is a good example of an RIA, although even it isn??™t perfect because
while it has definite advantages over a typical web site, it still looks and feels very much like a
web page, albeit one with lots of niceties mixed in.
