UDDI Registry Node. Designer displays the URL of the UDDI Registry to which you are connected next to the registry icon. Below the UDDI Registry name, Designer displays all of the business entities registered in that UDDI Registry.

Business Entity. A business entity is a publisher of web services to the UDDI Registry. Below the business entity name, Designer displays the web services published by that entity.

Web service. A web service is a software application that can be accessed remotely, using XML-based languages to communicate. From a web service or a WSDL, you can create a consumer web service descriptor and connector. Designer can invoke the connector to run the remote web service. From an existing IS service or WSDL, you can create a provider web service descriptor. You can then publish the web service descriptor to a UDDI Registry so that the IS service it describes can be invoked by an external user as an “operation” of the web service.
