Overview


  “A Web Service is an interface that describes
   a collection of operations that are network
   accessible through standard XML messaging.
   Web Services fulfill a specific task or a set of
   tasks…” (IBM)
  This service-oriented architecture must support:
  > Service Description
  > Publication
  > Discovery and Invocation
  > Composition, Orchestration, and Legacy Integration
Foundation Technologies


   The goal of a core set of foundation technologies
    is to provide a platform for application and
    business process integration.
   To date, the basis for a technology-neutral, standards-
    based environment includes:
   > SOAP: Simple Object Access Protocol
   > UDDI: Universal Description, Discovery, and
     Integration
   > WSDL: Web Services Description Language
Customer Examples


  Sybase customers are developing and
   implementing production Web Services
   applications today.
  Examples:
  > For Application Integration and Collaboration in the
    financial services industry (mutual funds).
  > To provide Common Services over the Web (service
    bureau model for outsourced applications).
