What technologies and standards are used to develop Web services and how do they relate to each other?

What will be an ideal response?

Key to the Web services approach is the use of widely accepted technologies and standards, such
as:
? XML (extensible Markup Language).
? SOAP (Simple Object Access Protocol) is a communication protocol for exchanging
structured information over the Internet and uses a message format based on XML. It is both
platform- and language-independent.
? WSDL (Web Services Description Language) protocol, again based on XML, is used to
describe and locate a Web service.
? UDDI (Universal Discovery, Description, and Integration) protocol is a platform-
independent, XML-based registry for businesses to list themselves on the Internet. It was
designed to be interrogated by SOAP messages and to provide access to WSDL documents
describing the protocol bindings and message formats required to interact with the Web
services listed in its directory.
