techniques for rapidly moving government services to the Internet
are well defined and require less than half of the time and cost of a few years
ago. The generalized strategy is defined below and illustrated in
the Rapid Deployment Graphic :
is the E-Government rapid implementation strategy:
- The E-Gov plan
identifies services to be moved to the Internet.
- Legacy systems are
reviewed to locate required data and identify formats and structures.
- Data that do not
exist or that are unusable, (e.g., paper files) will require new systems
- "Off the
shelf" data base software will be used to interface with legacy
systems, extract data and assemble it in staging servers for use in internet
applications. (The reverse of this process is used to update legacy
data from on-line systems.) See Data Warehouse
- A redundant firewall
(i.e., a firewall behind a firewall) protects legacy and other data by
forcing intruders into separate and unique authentication.
- Between firewalls,
web servers process requests from Internet users and execute internet
applications which in turn, request legacy data as required.
- The web servers
interact with Internet users to complete transactions.
- Finally, the public
user needs only a browser and a connection to the Internet in order to
conduct business with this newly on-line government agency.
