Goal

Web services are applications that are accessed over the net. Thus a web service can expose business logic that can be accessed by other applications. They allow data exchange and communication across different programming languages, platforms and operating systems. The methods or functions that a web service offers can be accessed remotely using SOAP or other XML based languages over the net. The functionality available from a web service is described in the XML based Web Services Description Language (WSDL) file.

For example, a bank account service may implement functions to identify the account number, IBAN (International Bank Account Number), account currency etc. The WSDL file is used to describe required parameter and the functions offered by a web service which can be invoked by any consumer. This means that all a consumer needs to know about a certain web service is held in the WSDL file that describes its functionality.

To use the web service, the consumer submits a request as a SOAP message to the web service provider and receives the response in the same format. In the above mentioned example the consumer can send a SOAP message including the bank account id 78 to the bank account service and receive the IBAN and currency in the response from the web service.
