RIAs (Rich Internet Applications) are Web-based applications. These applications function as traditional desktop applications. Web browsers are required for access. However unlike traditional applications, software installation is not required. Depending on the application one usually will need to have ActiveX, Java, Flash, or similar technologies installed on a client machine. Before RIAs began becoming popular, most web applications were composed of static pages.

Rich Internet Applications developed by the experts at Biztech offer superior accessibility, portability and scalability. With high levels of performance and reliability, the Rich Internet Application we provide give end users an optimal web experience.

If you want to have frequent improvements, SEO friendliness and customization, then go for AJAX. It helps you in revamping your existing website. One can add rich functionality with smaller and more frequent updates. With AJAX development frameworks, you can customize web applications for diverse requirements.

It is used for building larger and complex applications. It works best when high level of complexity and data processing is required. You can use Flex to tweak your existing web applications via widgets. Advantages include an optimized performance and easier code maintainability.

It is similar to Flex. Silverlight is used for large and more complex web application development. However, this is designed for the community of .Net developers and integrates well with .NET components.

JavaScript libraries provide a framework for an RIA application that leverages client-side scripting to handle front-end interface functions. These are more like jQuery and MooTools. They are basically JavaScript files that comprise of a collection of useful, cross-browser-tested functions for doing things with Ajax. They deal with common user interactions like hiding and showing content based on a user-driven event.

These libraries include RIA components like grids, graphs, and complex form elements, as well as utilities to handle Ajax. The best part is that most great JavaScript libraries for web development are open source.

ICEfaces handle all of the JavaScript/Ajax for web application via Java APIs. They extend the standard JavaServer Faces (JSF) framework. A Programmer’s workflow is greatly simplified by ICEfaces. Also, the task of creating RIAs is made simpler.

Adobe Flash Builder 4 is extremely interesting as it is cross-platform and cross-browser in nature. When compared with JavaScript, where browsers have varying JavaScript engines that handle and process your code, Adobe Flash has one engine that your users install via the Adobe Flash browser plug-in. It is possible for Flash Builder 4 applications to do this as they are embedded into HTML pages, meaning that the browser itself has no effect on the application’s performance. This means that one can run even the most complex web applications correctly in IE6 if one wants to.

HTML5 has been the latest development in the RIA movement. It is a blend of HTML4, JavaScript, CSS, JavaScript libraries and Flash into a single specification that leverages the API model.
