What is a web service?

A web service can ideally be defined as independent modular self-describing application function or service. On the very basis of XML standards, this application function can be described, made available, located or called using the internet protocols. Each of them thus is endowed with a particular piece of functionality that can be used.

Who is a web service provider?

Usually an entity who aids to provide web services to a business system is termed to be a service provider. The provider is usually seen to have a corresponding XML-based description of the web service in the WSDL document. Thus, on the basis of the HTTP transport protocol, SOAP is established as the quasi-standard access protocol.

The process of publishing web service.

The process of publishing of a web service is taken care by the service provider. The service provider transmits information about itself and a description of the offered service to the services registry. A service register can be defined as a type of yellow page for web services. Along with other data, it also provides information on calling the web service.

The standard register used is the UDDI services registry. SAP provides a public UDDI server which can also be called by an ABAP client as a service registry.

Web service consumption.

Ideally, the user of a web service is called service consumer. Mostly, the service consumer happens to be an application that accesses the web service. The application obtains the necessary information for this from the service description.
