Applying WebSA to a case study: A travel agency system

Web engineering research community has proposed several web design methods that have proven successful for the specification of the functional and navigational requirements posed by Web information systems. However, the architectural features are often ignored in the design process. This situation causes Web applications with rigid and predefined architectures depending on the Web design method the designer is applying. To overcome this limitation, we propose a generic approach called WebSA. WebSA is based on the MDA (Model-driven Architecture) paradigm. It proposes a Model Driven Development made up of a set of UML architectural models and QVT transformations as a mechanism to integrate the functional aspects of the current methodologies with the architectural aspects. In this paper, we apply WebSA with the OO-H method using as a running example the Travel Agency specification.
