3 Traditional Scenario GCM system Satellite Info System Geo-science Information Systems

4 A enabled Scenario GCM system Satellite Info System Utilises HTTP,, MIME technologies Geo-science Information Systems Portal/ Warehouse Architectural Concerns: Autonomy of Information Systems Single point of failure Scalability of the system Extensibility of the system Appl icat ion

5 A Services enabled solution GCM system Satellite Info System Utilise SOAP, WSDL,, HTTP technologies Services Services Services Geo-science Inf or mat ion Syst ems Interoperability Concerns: Standard services interface Standard data models Standard data encoding Appl icat ion

6 An extended Service GCM system Service Satellite Info System Service Geo-science Inf or mat ion Syst ems Scenario Benefits: Strengthen systems reusability De-couple demanding tasks of complex applications Enable co-operative work Strengthen systems autonomy Appl icat ion #1 SVG XSD Servers/Services (Presentation Information) Facil it at or #1 Service/ Servers Facil it at or #2 Service/ Server Facilitating Services Concerns: Standard services interface Standard data models Standard data encoding Appl icat ion #2 Thick Client Application Thin Client Application Thick Client Application
