The system design is designed based on our previous work
in [11], that was developing a web-based ES with web and
WAP application for consultation application. The system was
utilizing an arbitrary database for holding knowledge base
representation. Therefore the system is accessible through web
and W AP interfaces. The usage of the database also allows
experts or knowledge engineers to carry out data entry or
editing process through web interface. An expansion for SMS
based consulting application is done by adding a software that
will act as SMS server and gateway. Furthermore, explanations
regarding system design will be divided into knowledge base
representation and system architecture, which is expanded
using SMS, based consulting application.
