The 6th factor: the RIA domain chart

A real case study: YouThru.com

Before starting.. We’ll start from this assumption : It’s a fact that Rich Internet Applications give developers and web users innumerable benefits respect HTML applications The problem is to decide the path to take Choosing the final RIA path Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

Choosing the final RIA path What is a RIA Excerpt from : Banks Eye Rich Internet Applications to Replace Web Applications Gartner, Stessa B Cohen, Mark Driver, Dec 05 RIA technology is a distributed Web application that breaks the model of "coarse-grain" HTTP request/response . RIA applications handle content with visual interaction to deliver dynamic data to the client faster , while providing a richer user experience . Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

Choosing the final RIA path What makes a RIA

Choosing the final RIA path Benefits of a RIA It allows the user to access a Web site or application without a separate installation process. It offers a rich user interface that matches the look and feel of a native graphical user interface (GUI) over a browser. The applications themselves are small , providing reasonable performance for slower dial-up users as well as broadband connectivity.

Factors Choosing the final RIA path When choosing a RIA technology you should consider the following factors: The reach (browsers, plugins …) Open Source over Commercial product Internal knowledge Development time (time to market) Community and Support infrastructure Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

When choosing a RIA technology you should consider the following factors:

The reach (browsers, plugins …)

Open Source over Commercial product

Internal knowledge

Development time (time to market)

Community and Support infrastructure

Choosing the final RIA path AJAX AJAX (Asynchronous JavaScript and XML), is a web development technique used for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes so that the entire web page does not have to be reloaded each time the user requests a change. Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

Choosing the final RIA path AJAX, how it works AJAX uses a combination of: XHTML and CSS, for styling information. DOM accessed with a client-side scripting language (usually JavaScript) The XMLHttpRequest object, used to exchange data asynchronously with the server. XML is sometimes used as the format for transferring data between the server and client ( any format will work, including preformatted HTML, plain text and JSON) Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

For a start up it’s very fast to adopt AJAX

Choosing the final RIA path AJAX, Disadvantages AJAX could require a consistent time in testing and debugging Choosing a commercial AJAX solution means adopting a proprietary framework and tool The AJAX market is very fragmented The community is big but has caused a lot of confusion. There’s no official voice to follow. Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

Choosing the final RIA path How can I choose Disclaimer : Each RIA techonology is GOOD .... Not GOD ! Don’t think that there is the perfect technology that fits all your needs for every projects. “ With great power comes great responsibility.” by Benjamin Parker, Spiderman’s Uncle Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com

Bla bla bla bla Tips Usability For its nature a RIA can easily fall into bad usability. When developing and designing a RIA pay attention to usability aspects. Add visual clues, icons, graphics, error handling, user messages and so on. Choosing the final RIA path One page app A RIA is able to embed many task flows in a single page. This is great but can cause a lot of problems. It requires a deep understanding of the technology you are using. Comtaste Srl – www.comtaste.com – Marco Casario m.casario@comtaste.com
