The Expressive Power of UML-based Web Engineering1

UML-based Web Engineering (UWE) is a development process for Web applications with focus on systematic design, personalization and semi-automatic generation. UWE describes a systematic design methodology using exclusively UML (Unified Modeling Language) techniques, the UML notation and the UML extension mechanisms. In this article we show the power of this approach. On the one hand, UWE prescribes how to build navigation and presentation models for Web applications defining therefore special UML stereotyped modeling elements and tagged values. On the other hand, we show how these Web specific navigation and presentation models can be supplemented by other views using the variety of UML diagram types and UML modeling elements. Our current research activities focus on the dynamic aspects of the design of Web applications, such as task modeling and modeling of Web scenarios, graphical representation of the distribution of Web components and semi-automatic generation of Web applications based on design models.
