In order to satisfy an increasing need to respond
rapidly to changing business requirements and knowledge,
and to reduce implementation cosfs. the mainstream
business world is progressively relying on the experf
sysfems technology. In addition, recenf e-business
iniriatives are requiring companies to provide “web-
enabled” systems in order to maintain a competitive edge
in their marketplace. In this paper, we describe our
experience in capturing the business logic and
implementing a web-based expert system for vehicle
registration fee compufafion af California Deparrmerif of
Motor Vehicles. The system has been implemented using
the Blaze Advisor rules engine and has been deployed to
Sun’s JZEE Reference Implemenfafion of a Java
application server. Our work has shown that using expert
system technology to implement a web-based, business-
driven solution is certainly a viable and promising option.
Deployment of the rule service as an Enterprise JavaBean
exposes the rulebase to various @pes of business clients,
andprovides a consistent and adaptable implementation of
the business domain
