Web System Trace Model Using a Web Application Architecture Framework

Traceability analysis is crucial to the development of web-centric systems, particularly those with frequent system changes, fine-grained evolution and maintenance, and high level of requirements uncertainty. A trace model at the level of the web system architecture is presented in this paper to address the specific challenges of developing webcentric systems. The trace model separates the concerns of different participants in the web development life cycle into perspectives; and classifies each perspective into structure, behaviour and location. Tracing relationships are presented along two dimensions: within perspectives; and among perspectives. Examples of tracing relationships are presented using UML. 1
