EXPERT RESPONSE
Boy, do you ask the hard questions!
SOAP is an XML protocol. (What's an XML protocol?) An XML protocol is an XML
messaging format that you can use to send information from one application to another application.
To put it simply, SOAP and its related technologies (WSDL, UDDI, etc.) form
the foundation for a new type of middleware for application-to-application
integration -- I usually refer to it as Intenet Middleware. SOAP lets you do
application-to-application integration over the Web. Unlike previous
middleware technologies (e.g., DCE, CORBA, DCOM, RMI, MOM, etc.) SOAP
middleware is available on any platform, and it supports any programming
language.
