Professional XML Web ServiceseBook - 2004
Web Services are self-describing, modular applications. The Web Services architecture can be thought of as a wrapper for the application code. This wrapper provides standardized means of: describing the Web Service and what it does; publishing it to a registry, so that it can easily be located; and exposing an interface, so that the service can be invoked - all in a machine-readable format. What is particularly compelling about Web Services is that any client that understands XML, regardless of platform, language and object model, can access them.
