6.6.1. What is UDDI? ¶

UDDI is a platform-independent framework for describing services, discovering enterprises, and integrating enterprise services by using Internet.

• UDDI refers to general description, discovery, and integration services

• UDDI is a directory used to store information about web services.

• UDDI is a directory of web services interfaces described by WSDL.

• UDDI communicates via SOAP

• UDDI is built into Microsoft’s .NET platform

6.6.2. What is the basis of UDDI? ¶

UDDI uses W3C and IETF* Internet standards such as XML, HTTP, and DNS protocols.

UDDI uses WSDL to describe the interface to web services

In addition, by using SOAP, you can also achieve cross-platform programming features. As we all know, SOAP is the protocol communication specification of XML, and relevant information can be found on the W3C website.

Note: IETF-Internet Engineering Task Force

6.6.3. Benefits of UDDI ¶

Any industry or enterprise of any size can benefit from UDDI.

Before UDDI, there was no Internet standard for enterprises to provide information about their products and services to their enterprises and partners. There is no way to integrate into each other’s systems and processes.

The problems that the UDDI specification helps us solve:

• Makes it possible to find the right enterprise among millions of enterprisescurrently online

• Define how to start a business once the preferred enterprise is discovered

• Expand new customers and increase access to current customers

• Expand sales and extend market reach

• Meet user-driven needs to remove barriers to rapid cooperation in the globalInternet economy

6.6.4. How UDDI is used ¶

If the industry publishes a UDDI standard for flight ratio testing and booking, airlines can register their services in a UDDI directory. The travel agency can then search the UDDI directory to find the airline reservation interface. When this interface is found, the travel agency can immediately communicate with the service because it uses a well-defined booking interface.

6.6.5. Who is supporting UDDI? ¶

UDDI is a cross-industry research project driven by all major platforms and software providers, such as Dell, Fujitsu, HP, Hitachi, IBM, Intel, Microsoft, Oracle, SAP, and Sun. It is not only a group of market operators,but also a leader in e-commerce.

Hundreds of companies have joined the UDDI group.
