Web Services

These are defined by the W3C as
"a software system designed to support interoperable Machine to Machine interaction over a network." Web services are frequently just Web APIs that can be accessed over a network, such as the Internet, and executed on a remote system hosting the requested services.

QMS are now developing web services that communicate using XML messages that follow the SOAP standard. In such systems, operations offered by the service written in the WSDL (Web Services Description Language), offer definitive user interactions across the web.
