WebSI

I was one of the main contributors and I developed my Ph.D. Thesis on WebSI. The aim of WebSI Project was developing three suites of tools for building data-centric and service-centric Web applications. The Web Site Design Suite focused on tools to assemble Web applications at high-level, and on the integration of traditional Web conceptual modelling methods with Web services and workflows. The Service Composition Suite provided composition abstractions in order to integrate Web Service calls into complex conversations. The Data Integration Suite provides primitives for collecting and integrating data from multiple sources, using XML and Xquery. The three tool suites were usable in an ASP Infrastructure layer, which provides the hosting of internal services and databases. Three applications in different business scenarios were developed to help focus the design on real problems, to demonstrate the WebSI technology, and to ensure market needs feedback.
