Know Everything About Rich Internet Application (RIA)

In this article, we are giving you basic details about Rich Internet Application so you can understand how this technology can enhance performance of desktop applications.

Rich Internet Application (RIA) is basically web-based applications that consist of some characteristics of graphical desktop applications. RIAs are designed with powerful development tools such as AJAX, Adobe Flash, Flex and Adobe Integrated Runtime (AIR), Microsoft Silverlight, Curl (an object-oriented language with embedded HTML markup), Google Gears, OpenLaszlo and Webtop and Oracle WebCenter to make it them run faster and be more engaging.

This combination of the latest technologies ensures better visual experience and more interactivity than traditional browser applications built using HTML and HTTP.

Here are the most sought-after characteristics of RIAs that differentiate the technology from conventional web applications.

Direct Interaction

In a traditional page-based web application, you usually find limited interaction to a small group of standard controls. On the other hand, an RIA uses a wide range of controls that commits excellent user experience. For example, users can easily access to page’s elements through edit and drag-and-drop tools.

Partial-page updating

One HTML-based webpages are loaded, they needed to send back to the server if you want to make any changes. This process can be hampered by network connectivity issues and processing limitations, which further compels users to wait while the entire page reloads. You can easily update RIAs-based webpages without any hassle as they incorporate latest technologies such as real-time streaming, high-performance client-side virtual machines, and local caching mechanisms that significantly reduce wait time while enhancing responsiveness.

Excellent Feedback

RIAs are able provide fast and accurate feedback, real-time confirmation and informative, detailed error messages due to ability to change parts of pages with no need of reloading.

Consistent look and feel

Leveraging RIA tools, you can provide your users ultimate experience with different browsers and operating systems with more consistency.

Offline use

If the desktop application is designed to retain its state locally on the machine, it can be accessed easily even absence of connectivity.

Performance Impact

Depending upon the application and network characteristics, RIA-based tools can perform better than conventional apps. The applications that avoid round trips to the server will perform better. Further, offloading to the client device improves server performance.
