Web services are enterprise applications
that use open, XML-based standards and transport
protocols to exchange data with calling
clients.
IT operations are quickly
ramping up Web services projects to preserve
existing investments in mainframes and other
legacy systems by unlocking their data for
use in new Web-based applications.
A Web service is a software
system designed to support interoperable
machine-to-machine interaction over a network.
It has an interface described in a machine-processable
format. Other systems interact with the
Web service in a manner prescribed by its
description using SOAP messages, typically
conveyed using HTTP with an XML serialization
in conjunction with other Web-related standards.
Software applications written
in various programming languages and running
on various platforms can use web services
to exchange data over computer networks
like the Internet in a manner similar to
inter-process communication on a single
computer.
