Usable Rich Internet Application Architecture:
My article on usable RIA architecture got published on Sitepoint. The article lists various usability constraints in the first two pages and later introduces a design pattern to introduce these constraints into the design process while designing rich internet applications.
Design constraints: There are certain basic likes and dislikes that users have with various types of interactions. Various things that users hate are: learning, repeating, waiting, searching, reading, security breaches, monotonous look, platform restrictions, rigid functionality and mistakes.
The design pattern: Dividing the application into pages and navigation will help. Each page is composed of data, components, logic, and presentation. The pages are encapsulated in the navigation shell, which again has data, components, logic and presentation. The complete article is available here.
