Service Oriented Architecture
There has been much recent interest in service-based architectures as a very promising means to structure software development. This represents a convergence of simple ideas from the world of objects with other concepts in distributed systems and component-based development, underpinned by cross-platform protocols based largely on XML.

The course aims to give the student an understanding of the strengths and weaknesses of a service-based architecture, informed by an ability to implement and deploy simple web services using a suitable development platform. They will also learn to define and design applications as combinations of services, and be able to discuss the emergent properties of those compositions; and to understand the research context and potential future directions for these technologies.

The course presupposes a basic understanding of XML schema and XML namespaces. Practical exercises entail a considerable amount of Java programming; fluency with some OO programming language will be helpful, and participants may want to read up on Java beforehand if not familiar with it. The design discussion assumes a basic knowledge of UML.
