This Monday the San Francisco Bay Area F# Meetup will be hearing from Jon Harrop on the topic of “Building a customizable business rules engine with F#“
Business rules are the core of business applications; yet, once an application is deployed, it is often cumbersome and expensive to update existing rules. This problem is particularly important in some industries, like finance, where new products, which require new rules, are introduced on a regular basis. In this talk, Jon Harrop will demonstrate how F# can be used to address that issue. Jon built a bespoke business rule engine with F#, using pattern matching and his own lexer/parser/interpreter, which allows users to define, manipulate and test rules in real time, in a live application, using a WPF user interface – under 800 lines of F# code.
Dr Jon Harrop, BA MA MSci PhD (Cantab), is the managing director and co-founder of Flying Frog Consultancy.
