What is Universal Description, Discovery, and Integration (UDDI) in Web Services
Technology & Science / March 5, 2018

Universal Description, Discovery and Integration (UDDI) protocol is one of the major building blocks required for successful Web services. UDDI creates a standard interoperable platform that enables companies and applications to quickly, easily, and dynamically find and use Web services over the Internet (or Intranet). UDDI is a technology for publishing, querying, finding, and invoking Web services using a registry that provides data, metadata, and pointers to these services. Overview Universal Description Discovery and Integration (UDDI) is a standard sponsored by OASIS (Organization for the Advancement of Structured Information Standards). Often described as the yellow pages of Web services, UDDI is a specification for creating an XML-based registry that lists information about businesses and the Web services they offer. UDDI provides businesses a uniform way of listing their services and discovering services offered by other organizations. Though implementations vary, UDDI often describes services using WSDL and communicates via SOAP messaging. Registering a Web service in a UDDI registry is an optional step, and UDDI registries can be public or private (i.e. isolated behind a corporate firewall). To search for a Web service, a developer can query a UDDI registry to obtain the WSDL for the service he/she wishes to utilize….

What is Web service Discovery Language in web Services

Web Services Description Language (WSDL) is a format for describing a Web Services interface. WSDL describes a web service at both an abstract and a concrete level. At the abstract level, the web service is described by the messages it sends and receives. Typically an XML Schema is used for this. At the concrete level, the web service’s transport and wire format for one or more interfaces are described. Overview of Web Services Description Language WSDL is an XML-based format for describing Web services. Clients wishing to access a Web service can read and interpret its WSDL file to learn about the location of the service and its available operations. In this way, the WSDL definition acts as the initial Web service interface, providing clients with all the information they need to interact with the service in a standards-based way. Through the WSDL, a Web services client learns where a service can be accessed, what operations the service performs, the communication protocols the service supports, and the correct format for sending messages to the service. A WSDL file is an XML document that describes a Web service using six main elements: The WSDL document that describes a Web service acts as…
