Basics
Web Services ermöglichen Kommunikation zwischen Applikationen übers Internet. Während bisher bei verteilten Systemen die elektronische Kommunikation über Rechnergrenzen hinweg meistens per CORBA, RMI oder DCOM erfolgte, nutzen Web Services einfaches XML, meistens über HTTP.
- XML Web Services expose useful functionality to Web users through a standard Web protocol. In most cases, the protocol used is SOAP.
- XML Web services provide a way to describe their interfaces in enough detail to allow a user to build a client application to talk to them. This description is usually provided in an XML document called a Web Services Description Language (WSDL) document.
- XML Web services are registered so that potential users can find them easily. This is done with Universal Discovery Description and Integration (UDDI).
