[rules-users] Could anyone suggest alternate approach

Please ignore my previous email as I did not include subject. I have 4 drl files in my app. Loading all the 4 during application startup. If any rule is satisfied in File 1,I don't want File 2 be called.Should execute File 3 and 4. Similarly If rules in File 1 is not satisfied,want to call File 2 then File 3 and 4. At present I am doing this way.Please let me know if this is ok or if there is any better solution. Set an attribute when a rule is satisfied. (attribute is not dummy,I need it in my app) Attribute is checked in each and every if it is null. Example File1.drl contains 2 rules.If first rule is satisfied, don't want to execute second rule.So setting rule with a valid number. File1.drl rule "1.Age Factor and Junior" when d : CustomerDetail( rule == "" && sale == 'Junior' && age in ("16","17")) then System.out.println("Junior and Age Satisfied "); d.setRule("1"); end rule "2.Junior only Age Factor" when m : CustomerDetail( rule == "" && age in ("16","17")) then System.out.println("Only junior Age satisfied."); m.setRule("2"); end File2.drl rule "3.Age Factor and Senior" when d : CustomerDetail( rule == "" && sale == 'Senior' && age in ("70","75")) then System.out.println("Senior and Age Satisfied "); d.setRule("10"); end rule "4.Senior only Age Factor " when m : CustomerDetail( rule == "" && age in ("70","75")) then System.out.println("Only senior Age satisfied."); m.setRule("11"); end This one works but I see these disadvantages: 1)If the rule 1 is satisfied, rule2 is still executed.Similary all the rules in File2.drl. 2)Might impact performance all the 4 rules are called all time. Any suggestions?
