This unit introduces some of the latest developments in the field of web applications. Known as Web Services, they make use of a number of standards to allow business to business(B2B) systems over the world wide web. Web services aim to resolve the issues that arise when different service providers use different languages and data types and run on different operating systems. Resolving these problems comes under the broad title of interoperability. A number of technologies and standards allow Web services to be employed. These include XML for description of Web services, SOAP as the protocol to send messages, WSDL to describe the operations offered by a Web Service, BPEL to co-ordinate a number of Web Services in complex synchronous and/or asynchronous interactions, and UDDI as registry to allow discovery and publication of Web Services. This emerging area will assume greater importance for applications in commerce and the related IT research over the coming years.

This unit has been updated as part of a 2009 review and comparison of data with current Handbook, Syllabus + and Callista data.

30/11/2017 - Unit disestablished at FEC 5/17 Item 7.3.

This is a core third level unit in the Bachelor of Information Technology and Systems (BITS) major in Internet Systems. Web services and XML technology are an important part of systems development in the current IT environment. Students undertaking a Systems Development require skills in this area.

At the completion of this unit students will:

• create and validate XML documents based on XML Schema;
• map organisational rules into XML Schema definition;
• be able to retrieve XML document using XSLT;
• understand the different architectures provided by different component technologies and their evolution towards service oriented computing;
• be able to create and deploy web services as an example of service oriented computing application;
• know the technologies and standards that enable web technologies including XML, SOAP, WSDL and UDDI;
• understand the issues of choreographing a number of web services into a business process
• possess the skills necessary to design and develop software components;
• be able to design and develop programs that utilise the services and facilities offered by component architectures.
