Use of Logic Programming for Complex Business Rules

  • Walter G. Wilson
Part of the Lecture Notes in Computer Science book series (LNCS, volume 3668)


This paper describes the move from a proprietary mainframe application to open systems application running the 360 º Fares System whose business logic component is implemented in Prolog. It is one of the largest and most profitable Prolog applications written. Prolog is the business-rule component in a multi-component application that includes network, user interface, security data access tiers. There has been no downtime, scheduled or unscheduled, in the 360 º Fares System since June 2004.
