2.2.9 Web Service
Menurut Tatnall (2005), Web Service—A Web service is a program that accepts
and responds to requests over the Internet. Typically, a Web service accepts requests in
an XML-based format. The actual format of the request and the response depends on the
XML standards that are being used. One such standard is SOAP. There are public
registries and languages—such as UDDI, WSDL—which are used to catalog the
different available Web services (see Appendix). A calling program can query the
registry (UDDI) to find an appropriate Web service, then use WSDL to figure out which
parameters the service needs, and finally use a calling protocol and XML standard like
SOAP to actually make the call to the Web service.

on distributed computing
technology and provide a standard means of interoperating between different software
applications
across,
and
within,
organizational
boundaries,
using XML protocols and
formats.
