Rich Internet Application
Rich Internet applications (RIA) are web applications that have the features and functionality of traditional desktop applications. RIAs typically transfer the processing necessary for the user interface to the web client but keep the bulk of the data (i.e., maintaining the state of the program, the data etc) back on the application server. RIAs run in a web browser and do not require software installation.
I work on RIA for two years. Here is some section excerpted from the project I made for Siriraj Hospital. To see my work on RIA, click here.
