Module code: CO4214
A Web service is an application component deployed on a Web accessible platform, provided by a service provider to be discovered and invoked over the Web by a service requestor. Service-oriented architectures, the underlying architectural style of Web services, combine ideas from component-based and distributed systems, adding the idea of services as loosely coupled components that may be discovered and linked at runtime. Applications range from enterprise application integration, via electronic commerce, to dynamic e-business scenarios.
Lectures will give an introduction to the underlying basic technologies of Web services and present a systematic, model-based development approach using the UML. This includes the specification of service interfaces by means of UML diagrams, the systematic (and partly automatic) generation of the corresponding XML-based descriptions, and the implementation of services in Java.
