Web Services: Why and How
Francisco Curbera, William A. Nagy · 2001
Web services are a natural consequence of the evolution of the Web into an open medium which facilitates complex business and scientific application interactions. Web services are concerned with the problems of enabling systematic application-to-application interactions over the Web, and the integration of the existing network computer infrastructure into the Web. The key components of this work are a focus on interoperability, support for e#cient application integration, and the creation of a uniform representation of applications within heterogeneous distributed systems.
