A web service uses HTTP (Hypertext Transfer Protocol) and SOAP (Simple Object Access Protocol) to transfer the data between the service and the client.
Consumers of a Web Service do not need to know anything about the platform, object model, or programming language used to implement the service; they only need to understand how to send and receive messages.
