is a standard language used to describe the services offered and the functionality pro-
vided by each service.
So how is a web service used? Two enti-
ties collaborate with each other in a web
service implementation: the web service
consumer and the web service provider.
A web service provider provides the inter-
face and implementation for the web
services it provides through SOAP, while a
service consumer is a software that aims
at achieving a business objective (i.e. per-
forming a task) that can be accomplished
with the use of a web service. Each web
service provider registers its service in a
web services directory, next, the web ser-
vice consumer searches the directory for
a web service that can be used and inte-
grated to achieve the business objective
(UDDI).
There is a number of web service pro-
viders. Such providers include Google,
Amazon, eBay, PayPal, and FedEx. A web
service can perform simple tasks such as
calculations, google calendar operations,
weather forecasts to more advanced
tasks such as data transfer between
applications and performing banking
transactions.
In short, web services provide means of
integration, agility, and reusability for
enterprises and can greatly enhance
business operations.
