The term
web service
refers to a web-accessible application that performs some action based on a request from a client. For these entities to communicate, an agreed upon language, or communication protocol, must be used. The first web services used the Simple Object Access Protocol (SOAP), which is an XML-based messaging protocol. Although SOAP is effective, it is often perceived as being a heavyweight and difficult to use.
