The term Web services describes a standardized way of
integrating Web-based applications using the XML, SOAP, WSDL and UDDI open
standards over an Internet protocol backbone. XML is used to tag the data, SOAP
is used to transfer the data, WSDL is used for describing the services available and UDDI is used for listing what services are
available. Used primarily as a means for businesses to communicate with each
other and with clients, Web services allow organizations to communicate data
without intimate knowledge of each other's IT systems behind the firewall.
Unlike traditional client/server models, such as a
Web server/Web page system, Web services do not provide the user with a GUI.
Web services instead share business logic, data and
processes through a programmatic interface across a network. The applications
interface, not the users. Developers can then add the Web service to a GUI
(such as a Web page or an executable program) to offer specific functionality
to users.
Web services allow different applications from
different sources to communicate with each other without time-consuming custom
coding, and because all communication is in XML, Web services are not tied to
any one operating system or programming language. For example, Java® can talk
with Perl, Windows applications can talk with UNIX® applications.
