Distinguish between Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and Universal Description, Discovery, and Integration (UDDI). SOAP (Simple Object Access Protocol) presents a general messaging layout designed for web services. SOAP facilitates objects those do not recognize one another to swap messages. UDDI (Universal Description, Discovery, and Integration) gives a standard approach to de-register, register, and look up services on web services. A UDDI registry facilitates requestors to search services and suppliers to register their services. Once any requestor locates any service, the registry is of no use among provider and requestor.
