A transformational approach to produce web application prototypes from a web requirements model

There are a significant number of proposals for modelling and developing web applications, but very few of them rigorously deal with how to elicit and represent requirements, and how to go from the Requirements Model to the Conceptual Model with a sound methodological basis. This work presents an approach to capture web application requirements. The main goal of this approach is to provide analysts with techniques that allow them to specify not only the functional and data requirements of a web application but also the navigational ones at early stages. These techniques make it possible to identify, specify and describe every task that must be achieved by web application users. In addition, we introduce a strategy based on graph transformations that allow us to automate the derivation of the navigational model of the OOWS method from early requirements specifications. Finally, by using the OOWS automatic code capabilities, we show how this graph transformations-based strategy allows us to obtain web applications prototypes from early requirements specifications.
