A Web service is an application that has industry-standard protocols which requires using Web Services Description Language (WSDL) and sent to the application using Simple Object Access Protocol (SOAP) over HTTP (or HTTPS).

In a web service XML is used to tag the data, SOAP helps to transfer a message and WSDL is used to describe the availability of service.
