9. Web Portal Presentation Web site architectural goals: Reuseable(components & tools built for this application can be used elsewhere) Interoperable(use common standards/protocols) Expandable(new surveys can be added & new datasets & map layers for a survey) Redeployable(portal can be moved & run as an appliance)

10. Web Portal Presentation Fundamental approach: ABSTRACTION data managed in scattered/remote databases (by appropriate experts) data accessed & supplied centrally (few points of access) simple web portal kept separate from data sources data sources reuseable

11. Web Portal Presentation Fundamental approach: ABSTRACTION Portal Data server DB INTERNET
