A typical Web Service accomplishment can impose on multiple techniques, multiple object modes and multiple programming languages. By reason that the accomplishment of Web Service adopts SOAP, HTTP and XML, so the speciality of Web Service is that it can accomplish interoperability under different surroundings.
