The service registry is a server that acts
as a repository, or ???yellow pages???, for software interfaces that are published by service
providers.
Once a Web service is published, a service requester may find the service via the UDDI
interface (find operation). The UDDI registry provides the service requester with a WSDL
service description and a URL (uniform resource locator) pointing to the service itself. The
service requester may then use this information to directly bind at run-time to the service
and invoke it (bind operation).
Web.Services.Development.Life.Cycle
The Web services development life cycle may be summarized into four phases for each
role described above. These phases are: design and implementation, deployment, run-time
execution, and management. Each role has particular requirements for each phase of the
development life cycle.
1. Design.and.implementation: This phase includes the design, the specification of
the service interface description, and the development and testing of the Web service
implementation. Web service implementations can be provided by creating new Web
services, transforming existing applications into Web services, and composing new
Web services from other Web services and applications.
