Web services are not web applications. They are about the way we do with web applications. Foundation for Web Services includes:
- UDDI: publish, find, use services,
- WSDL: formal service descriptions,
- SOAP: service interactions,
- XML: universal data format, and
- the internet: ubiquitous communications.
The following are some good introductory reading about Web Services.
- The Essence of Web Services, written by Guillaume Pierre and Swaminathan Sivasubramanian,vrije Universiteit, in April 2004.
- Web Services Introduction from perfectXML.com. It is a very short one and contains good pointers.
