	<p><P>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.</P>
<h4>Frequency</h4>
<P>This subject has been discontinued; no further courses are planned.</P></p>
<h4>Objectives</h4>
<p>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.</p>

<h4>Requirements</h4>
<p>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.</p>
