Web Services WS 2004/05

Horizontal Tabs

General information
Wednesday 11:00am - 1:00pm Seminarraum 12 (SR12)

Like many other new technologies, Web services are still surrounded by a substantial level of noise. I.e. a lot of information is focusing on what could be done with Web services in the future, but on the other hand does not reveal what Web services can do today and in the short term. This seminar will describe the fundamental concepts behind the notion of Web services and present them as the natural evolution of conventional middleware, necessary to meet the challenges of the Web and of B2B application integration. Rather than focusing only on "how to write your first Web service" we will discuss the main objectives of Web services, the challenges that must be faced to achieve them, and the opportunities that this novel technology provides. Established, as well as recently proposed, standards and techniques (e.g., WSDL, UDDI, SOAP, WS-Coordination, WS-Transactions, and BPEL), are then examined in the context of this discussion in order to emphasize their scope, benefits, and shortcomings.
