Abstract. The goal of this work is to present the software WebRatio 5, which is a good representative of a new generation of CASE tools for model-driven design of Web applications. WebRatio 5 supports the WebML language and methodology, and exploits the implementation experience of previous versions of the software for providing user-friendly application design paradigms and reliable code generation engines. The tool is developed as a set of Eclipse plugins and takes advantage of all the features of this IDE framework. Moreover, it provides new capabilities in terms of support of extensions to the models, project documentation, and coverage of new phases of the development lifecycle. The overall approach moves towards a full coverage of the specification, design, verification, and implementation of Web applications.
Abstract. This paper presents WebRatio BPM, an Eclipse-based tool that supports the design and deployment of business processes as Web applications. The tool applies Model Driven Engineering techniques to complex, multi-actor business processes, mixing tasks executed by humans and by machines, and produces a Web application running prototype that implements the specified process. Business processes are described through the standard BPMN notation, extended with information on task assignment, escalation policies, activity semantics, and typed dataflows, to enable a two-step generative approach: first the Process Model is automatically transformed into a Web Application Model in the WebML notation, which seamlessly expresses both human-and machine-executable tasks; secondly, the Application Model is fed to an automatic transformation capable of producing the running code. The tool provides various features that increase the productivity and the quality of the resulting application: one-click generation of a running prototype of the process from the BPMN model; fine-grained refinement of the resulting application; support of continuous evolution of the application design after requirements changes (both at business process and at application levels).
