Web Services OverviewWeb Services OverviewWhat is a Service?What is a Service?
• Business Perspective– IT assets that correspond to
• Real-world business activities• Recognizable business functions• Accessible according to service policies established for the services
• Technical Perspective– Coarse grained, reusable IT assets– Well-defined interfaces (service contracts)
• Clearly separating the services’ externally accessible interface from the services’ technical implementation
• Web Services typically based on SOAP & XML– Note most OGC standard services are not SOAP based yet
Web services standards are implemented in products from all the major software vendors making web services the most prevalent approach to
implementing an SOA
Web Services OverviewWeb Services OverviewCore ComponentsCore Components
WebServices
SOAPWSDL
UDDI
• Service Description– WSDL
• Web Services Description Language• Defines all details about a service
• Service Protocol– SOAP
• How to format XML documents for transmission between applications
• Service Discovery– UDDI
• Universal Description, Discovery, and Integration• Not a requirement• Well proven for single Enterprise systems
These 3 technology standards, coupled with service-oriented design principles, form a basic XML-driven SOA

•• Web Services are not for everything!Web Services are not for everything!– Remote Procedure Calls (RPCs)– Missing Features (Compared to CORBA, COM, J2EE)
• Why?– Handle messages efficiently– Allow mapping to any distributed computing environment
