# WSDL UDDI * * * UDDI is a directory service that allows businesses to register and search for web services. UDDI stands for "Universal Description, Discovery and Integration," which can be translated as "Universal Description, Discovery, and Integration Service." It is an XML-based, cross-platform description standard that enables companies worldwide to publish their services on the Internet. * * * ## What is UDDI? UDDI is a platform-independent framework used to describe services, discover businesses, and integrate business services over the Internet. * UDDI stands for Universal Description, Discovery, and Integration. * UDDI is a directory used to store information about web services. * UDDI is a catalog of web service interfaces described by WSDL. * UDDI communicates via SOAP. * UDDI has been integrated into Microsoft's .NET platform. * * * ## What is UDDI Based On? UDDI uses Internet standards from W3C and IETF*, such as XML, HTTP, and DNS protocols. UDDI uses WSDL to describe the interfaces through which web services are accessed. Additionally, by adopting SOAP, it achieves cross-platform programming capabilities. As you know, SOAP is an XML-based communication protocol, and relevant information can be found on the W3C website. *Note: IETF - Internet Engineering Task Force* * * * ## Benefits of UDDI Industries and enterprises of any size can benefit from UDDI. Before UDDI, there was no Internet standard allowing businesses to provide information about their products and services to other businesses and partners. Nor did a method exist for integrating with each other's systems and processes. The UDDI specification helps solve the following problems: * Enables finding the right enterprise among millions of businesses currently online. * Defines how to initiate business once a preferred enterprise has been identified. * Expands new customer bases and increases access to existing customers. * Expands sales and broadens market reach. * Meets user-driven needs and removes barriers to facilitate rapid collaboration in the global Internet economy. * * * ## How UDDI Is Used Suppose an industry releases a UDDI standard for flight rate checking and booking. Airlines can then register their services in a UDDI directory. Travel agencies can subsequently search this UDDI directory to find airline booking interfaces. Once these interfaces are located, travel agencies can immediately communicate with these services using well-defined booking interfaces. * * * ## Who Supports UDDI? UDDI is a cross-industry research project driven by all major platform and software providers, including Dell, Fujitsu, HP, Hitachi, IBM, Intel, Microsoft, Oracle, SAP, and Sun. It also includes a group of market operators and e-commerce leaders. Hundreds of companies have already joined the UDDI community. AI is thinking...
