Webservice
WebService is a cross-programming language and cross-operating system platform remote calling technology.
The server program is written in java, and the client program can be written in other programming languages, and vice versa! It means that the server program and the client program can run on different operating systems.
XML+XSD, SOAP and WSDL are the three major technologies that constitute the WebService platform.
The SOAP protocol defines the format of the SOAP message. The SOAP protocol is based on the HTTP protocol. SOAP is also based on XML and XSD. XML is the data encoding method of SOAP.
A WSDL file is stored on a web server and can be accessed through a url address. Before the client calls a WebService, it needs to know the address of the WSDL file of the service.
