Rich Internet Application The term RIA (Rich Internet
Applications) refers to web applications that have the features and
functionality of traditional desktop applications, it means Rich Internet
Applications are a cross between web applications and traditional desktop
applications that shift some of the essential processing among the bulk of the
data for the user interface to the Web client while rest of some remain on
of RIAs RIAs are usually richer in functionality as they
offer user-interface behaviors using only the HTML widgets that can include
any technology being used by the client side, including drag and drop, using
a slider to change data, calculations performed only by the client and not
need to be sent back to the server.
Shortcomings And Restrictions of
RIAs Despite of having flair advantage
over the standard web application, RIAs have several shortcomings and
restrictions too. As RIAs run within a sandbox, so
the correct operation of sandbox is necessary to run RIA successfully. If
assumptions about access to resources are incorrect, RIAs may fail to operate
correctly that restricts access to system resources.
Rich Internet Application Development Traditional Web
applications displays in a series of Web pages that needs a distinct download
for each page, this is called web page paradigm. On the other hand RIA takes no
longer time in downloading the page because the client engine may be prefetching
some of the downloaded content for future use.
RIAs Methods And Techniques It is the first major client side language technology that has the
ability to run code and installed on several major of web clients. Earlier its
uses were relatively limited but the development in DHTML makes possible to
piece together an RIA system without using unified client-side solution. Ajax,
the advance tool of Java Script becomes more prominent technique to develop RIA.
