- Basic concepts in Web Services are SOAP, WSDL, DISCO, UDDI

SOAP : (Simple Object Access Protocol) SOAP is a communications protocol based on HTTP and XML using HTTP security

WSDL : (often pronounced whiz-dull) describes a set of SOAP messages and how the messages are exchanged  WSDL is a standard XML document, Files with the WSDL extension contain web
service interfaces.

WSDL files are used to communicate between web service producers and consumers.
A WSDL allows a client to utilize a web service’s capabilities without knowledge of the
implementation details of the web service.

WSDL.exe creates proxy classes which can be used as other general classes and we can create
objects and use the functionality of those objects to interact with webservice/ to consume the
webservice.

DISCO : Its a Microsoft standard for publishing and discovering Web Services. DISCO defines a document format alongwith to discover the Web Service (via documentation). The .disco file is created and placed in the root directory of webservice. Its not mandatory for working with DISCO.

UDDI : Universal Description, Discovery and Integration (UDDI) is a platform independent, XML-based registry for businesses worldwide to list their web services on the Internet. Its a place where you can find webservices for public
use. We can say its the yellow pages of Web services.
