Conclusion

Virtual Database technology is clearly critical technology with inherent impact on Universal Data Access, Distributed Computing and the emerging Information Age.

The Internet as the distributed computing medium of choice will continue to create insatiable demand for information. This simply increases the pressure on information producers and consumers to retrieve data and then rapidly convert into information at ever increasing rates.

Internet/Intranet/Extranet sites will emerge as the dominant medium through which information is exchanged. Information once obtained would then be rapidly converted in to knowledge the ultimate basis of competitive advantage and power.

If the Information Age is the next point of call, and we accept that all Information comes from data? Then it is rational to conclude that Virtual Databases will lie at the heart of the Information Age. In short, there is a limited Information Age at best without the prevalence of Internet/Intranet/Extranet sites driven by Virtual Database Engines.
