IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation Forrester Research on Web % of Fortune 1000 companies want to standardize on deploying browser applications* Browsers are catching up Still, majority of CIOs say the limits of HTML stops them* HTML is inflexible and Javascript is too complex Businesses are forced to trade off benefits of rich client vs Web2.0 applications EGL Rich UI intends to provide the benefits of both * Forrester Research – Urban Myth

IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation What is RichUI RichUI stands for Rich User Interface. This is a phrase commonly used when talking about an interface that provides dynamic rendering of its individual parts – notably, on the client-browser, as opposed to server-side processing It is a technology that will allow developers of any background to create rich web pages like one would see on a leading-edge, interactive site, such as: You might also have heard the term: Rich Internet Application (RIA)– which is often used synonymously with RichUI. The perceived benefits of RichUI or RIA include: Improved user-responsiveness The most successful RichUI implementations can achieve almost a Windows-desktop look and feel to users Rich-er functionality – beyond the simple rendering of HTML, to include dynamic widgets and components Improved browser/server load-balancing – as more of the business functionality can be distributed to the desktop (browsers)

IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation EGL Rich UI – Simple Example (Displaying Data)

IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation Rich UI Terms and Concepts – Rich UI and SOA services, and SOA Rich U.I. makes extensive use of services, and SOA – Service Oriented Architecture, which is a way to modularize and deploy code so that it can be consumed anywhere in the world using any language. There are two types of Web Service calls used by Rich U.I. 1.RESTful service calls 1.RESTful service calls – A call made through the HTTP service-interface. Once the call is made, a result is passed back to the requestor in XML or JSON format. 2.SOAP service calls 2.SOAP service calls - A type of service call that is more popular in enterprise. It requires the exchange of XML messages between the client and host system. By utilizing web services, one can create a truly scalable system.

IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation Terms and Concepts - continued AJAX AJAX – Stands for Asynchronous JavaScript and XML. RichUI makes extensive (almost wholesale) use of AJAX, utilizing it whenever it makes a service call. RichUI never executes a traditional HTML Form Submit. Widget Widget – A widget is a graphical unit in a GUI or Internet style interface. Most widgets allow for the interaction and manipulation of data in the browser. DOJO DOJO – An open source JavaScript toolkit. The DOJO project sets out to create widgets using only JavaScript. RichUI is able to interface with DOJO code in order to pull in some of their widgets.

IBM Software Group | EGL Simplify Innovation IBM Software Group EGL Simplify Innovation Terms and Concepts - continued JSON JSON – JavaScript Object Notation is lightweight format used by JavaScript to exchange data. JSON is able to serialize structured data, such as arrays, and exchange it among host and client machines. Silverlight Silverlight – is a new technology developed by Microsoft that is similar to Macromedias Flash. RichUI is able to interact with, and integrate with Silverlight widgets in your application:
