[rules-users] Data Modeling for medical expert system

Hi everybody, I am using Drools as a part of my Bachelor Thesis. My job is to build an expert system for medical diagnoses. My Question: Is there a best practice known in modeling a variable list of questions and answers in Drools? Up to now I modeled the list of questions implementing Java Classes and Enums for each question/answer pair. But to be able to change those options easyly I need a higher abstraction level than simple Java Classes and Enums. Could someone show me an example how to implement this? I hope I have explained my question understandable :) -- Dirk Conzelmann IT-Services Telefon: +49.179.2237995 Email: info(a)dirk-conzelmann.de Web: www.dirk-conzelmann.de
