Universal Description, Discovery, and Integration (UDDI) provides the definition of a set of services supporting the description and discovery of (1) businesses, organizations, and other Web Services providers, (2) the Web Services they make available, and (3) the technical interfaces which may be used to access those services. It discusses the role of a service registry focused on Web service change management from the Web service provider as well as from the Web service consumer perspective. They include: • Defining UDDI Nodes and Registries. Thomas Erl delves into the concepts and technology behind Web services, including Web services and the service-oriented architecture (SOA), Web Services Description Language (WSDL), Simple Object Access Protocol (SOAP), and Universal Description, Discovery, and Integration (UDDI).

The UDDI Project is based on existing Internet standards and it is platform independent and implementation neutral. In fact, it comes equipped with three UDDI features: A UDDI registry runs on every WebLogic instance, and can be used to store references to any web service. The Universal Description, Discovery and Integration (UDDI) specification defines a way to publish and discover information about web services. UDDI is a standard for describing, publishing, and discovering the web services that are provided by a particular service provider. The web service interface is described in a formal language like WSDL that allows creating code to access the service thus simplifying web service consumer (client) and provider (server) development.
