DynaRIA: A Tool for Ajax Web Application Comprehension

Thanks to Rich Internet Applications (RIAs) with their enhanced interactivity, responsiveness and dynamicity, the user experience in the Web 2.0 is becoming more and more appealing and user-friendly. At the same time, the dynamic nature of RIAs, and the heterogeneous technologies, frameworks, communication models used for implementing them negatively affect their analyzability and understandability, so that specific software techniques and tools are needed for supporting their comprehension. This paper presents DynaRIA, a tool for the comprehension of RIAs implemented in Ajax that is based on dynamic analysis and provides functionalities for recording and analyzing user sessions from several perspectives, and producing various types of abstractions and visualizations about the run-time behaviour of the application.
