High-Cost Strategy: If no downtime is acceptable, a much
more robust system can be created using SAN technology to T
store data and provide multiple levels of redundancy despite
storage device failure. All application servers would be set up
in redundant clusters so that if one fails, another immediately
takes over, resulting in zero downtime and full application
capability in the event of a single server failure. Data would
also be stored in a real-time remote storage facility utilizing an
external high speed network. In the event of a catastrophic
failure, all data would be safe and completely up-to-date
because of the remote facility's distance from the application
site. This is a very expensive approach, but supplies the utmost
in reliability, minimizes data loss, and reduces the amount of
time required to bring the system back up in the event of a
catastrophic failure.

6. CONCLUSION
Integrating prudent geo-spatial data management strategies
within the corporate IT infrastructure is becoming increasingly
critical in reducing bottlenecks associated with the multi-user, This s
multi-edit and multi-platform environments that utilities operate spatia
in. However, such integration must be intuitive, and should be and tl
structured to replicate existing workflow processes without variot
compromising data security. A careful mix of spatial data Synth
maintenance solutions, IT best practices and optimal hardware freque
configuration will meet this objective and provide the database multit
administrator with the generic framework required for chant
supporting business driven operations. CN
