Hi Nikhil, Drools implements the RETE algorithm. The "average" rules user does not need to bother or even care about it. All you need to do is use the rule engine(for which you do not need to design or write your own algorithm) and it will automatically do the work for you.

I concur everybody's statements fully. The purpose of a rules engine is to remove the need for the application developer to code algorithms to determine which of a set of rules should execute given a set of facts\properties\objects. Drools implements the RETE algorithm. Writing your own code to determine which rule should be executed would be like writing your own video driver so you can display an image. Of course "we" all assume you plan on using Drools as a rule engine; a black box to drive the execution of consequences based upon rule definitions and domain objects. As you state in your last post below; your "point is that [you] want to use rule engine in [your] application at it's fullest". Without a clearer description of your use-case it might be impossible for anybody to give an answer that helps with your particular issue. These forums are an excellent place to find solutions. Everybody has always been extremely helpful to me. I hope you are not discouraged by the responses received to date and am sure everybody is genuinely trying to help.

Hi Nikhil, Let's break down what you have said into pseudo Drools terms:- Rule 1 AdultFare(value==3000) ChildFare(value==2500) Then //Do what you want to do End Rule 2 ChildFare(value==2000) or InfantFare(value==1500) Then //Do what you want to do End Rule 3 AdultFare($f1 : value) InfantFare($f2 : value) eval($f1 + $f2 < 4000) Then //Do what you want to do End You suggest you have a RuleBase that has been successfully loaded. You state you have some attributes (I assume these to be implemented as Classes). StatefulSession ss = rulebase.newStatefulSession(); ss.insert( new AdultFare(1000) ); //<-- Causes object to be compared to ALL rules. This is how RETE works ss.insert( new InfantFare(1000) ); //<-- Causes object to be compared to ALL rules. This is how RETE works ss.fireAllRules(); //<-- Causes the "then" part of Rule 3 to execute It sounds like you are trying to hard.

Perfect this is the situation but the only difference is the last

Rulebase for all the 3 Rules are stored in memory. Now i have is attributes(implemented as bean class), but the issue is

know which Rulebase to use out of the three which is present in the

fetching them one by one and executing it individually is possible but

long procedure which i want to avoid.(executing 3 Rule is ok what if i

100000 rules it will be very slow process)

As you guys have suggested to combine all the rule base into one then for example(one which i have already mentioned) i will combine Rule1 , rule 2 and rule3 into 1 rule base then, when i pass the variables to the rulebase who will i come to know which rules were executed.

things i would like to know if i am going to execute this idea, the number of rules that i will using say around 100000, is it advisable to include all of them in to 1 rulebase!!! will there be any performance issues.

It appears that you want to reason about travel bookings or some such thing. You are thinking of the various attributes as individual (abstract) things that have a designation (such as "Adult Fare") and a value, with the intent to handle this with a set of facts, each of which has these two fields. While this "property list" view of data may have its merits, it complicates the writing of rules in system like Drools. Moreover, keeping this data in a map is fine from the Java point of view, but it leads to complications while processing it in DRL rules. (To say nothing about the poor performance due to eval all over the place.) I'm not sure about the relation between your Java class RuleAttributes and the HashMap instance hmAttriList, but even if the latter were an instance of the former (so it is a subclass of HashMap), it is questionable what the $a.Values["..."] returns - most likely not an Integer, and this is confirmed by the compiler's error message. Try to view a Booking as a Java Bean with attributes int numberOfAdults int numberOfChildren int childFare int adultFare boolean rejected and any other attribute of a booking you might want to put there. Create an instance of this bean and add it to Working Memory. A rule could now be written as rule "adt_chld_fare" no-loop true when $b: Booking( $af : adultFare, childFare > ($af - 1500) ) then modify( $b ){ setRejected( true ); } end There are many possible variations on this. Here is just one idea: You might not want to have the rejection being stored in the Booking bean, so you could, perhaps assert an instance of another suitably composed Bean class Rejection Booking booking String reason Much of the design depends on what and how you need to get the results of rule firing back to the application, so I won't continue. -W On Thu, Mar 19, 2009 at 7:52 AM, Nikhil_dev <k.nikhil(a)verchaska.com <mailto:k.nikhil@verchaska.com>> wrote: i have combined all the rules into a single RuleBase, below is the content of drl file, package com.vtech.ruleengine.module.rulemanagermodule import com.vtech.ruleengine.module.rulemanagermodule.RuleAttributes; import java.util.Map; rule "adt_chld_fare" dialect "mvel" when $a : RuleAttributes() eval ($a.Values["Adult Fare"]> ($a.Values["Child Fare"]+ 1500 ) ) then ($a.Values["AcceptRejectFilter"]='Reject') end rule "DEMO_RULE" dialect "mvel" when $a : RuleAttributes() eval ($a.Values["Adult Fare"]> 8000 ) then ($a.Values["Nett Payable"]= ($a.Values["Adult Fare"]* 0.80 ) ) end rule "Compare_date_1" dialect "mvel" when $a : RuleAttributes() eval ('12-Jan-2009'>='15-Jan-2008') then ($a.Values["Adult Fare"]= 5000 ) end rule "Rule_20090106_1" dialect "mvel" when $a : RuleAttributes() eval ( ($a.Values["No Of Adults"]< 10 ) && ($a.Values["No Of Adults"]> 5 ) ) then ($a.Values["Adult Fare"]= ($a.Values["Adult Fare"]+ -50 ) ) end rule "Rule_20090107_Markup" dialect "mvel" when $a : RuleAttributes() eval ($a.Values["markupPerc"]>= 0 ) then ($a.Values["markupAmount"]= ($a.Values["buyingAmount"]*$a.Values["markupPerc"]) ) end rule "Sample_Rule" dialect "mvel" when $a : RuleAttributes() eval ($a.Values["Sector"]< 0 ) then ($a.Values["Via"]= ($a.Values["Via1"]+ 1250 ) ) end i am passing following hashmap containing, hmAttriList.put("Adult Fare", 8000); hmAttriList.put("Child Fare", 80); hmAttriList.put("Gross Fare", 0); hmAttriList.put("Published Fare", 0); while executing it i am getting following error message SEVERE [global] org.mvel.CompileException: could not perform numeric operation on non-numeric types: left-type=null; right-type=java.lang.Integer at org.mvel.math.IEEEFloatingPointMath.doOperationNonNumeric(IEEEFloatingPointMath.java:149) at org.mvel.math.IEEEFloatingPointMath._doOperations(IEEEFloatingPointMath.java:102) at org.mvel.math.IEEEFloatingPointMath.doOperation(IEEEFloatingPointMath.java:43) at org.mvel.util.ParseTools.doOperations(ParseTools.java:810) at org.mvel.ast.BinaryOperation.getReducedValueAccelerated(BinaryOperation.java:21) at org.mvel.ExecutableAccessor.getValue(ExecutableAccessor.java:45) at org.mvel.ast.Substatement.getReducedValueAccelerated(Substatement.java:24) ............. .............. ==>[ActivationCreated(0): rule=adt_chld_fare; tuple=[fid:1:1:com.vtech.ruleengine.module.rulemanagermodule.RuleAttributes@14a0fe1] ] Error Message : org.mvel.CompileException: could not perform numeric operation on non-numeric types: left-type=null; right-type=java.lang.Integer ------------------------------------------------------------------------ _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Nikhil, there seems to be a communication breakdown here. Several people have suggested a solution that I believe fits your problem, but I'm not sure that you understand what they're saying. Generally, if I were dealing with a situation like this face to face, I'd have you summarize what others have suggested to see if you understood their ideas. Would you be willing to do that? --- On Fri, 3/13/09, Nikhil_dev <k.nikhil(a)verchaska.com&gt; wrote: > From: Nikhil_dev <k.nikhil(a)verchaska.com&gt; > Subject: RE: [rules-users] Identify Rule on Attributes > To: rules-users(a)lists.jboss.org > Date: Friday, March 13, 2009, 7:16 AM > Perfect this is the situation but the only difference is the > last part, > > Rulebase for all the 3 Rules are stored in memory. > > Now i have is attributes(implemented as bean class), but > the issue is i dont > know which Rulebase to use out of the three which is > present in the memory, > fetching them one by one and executing it individually is > possible but a > long procedure which i want to avoid.(executing 3 Rule is > ok what if i have > 100000 rules it will be very slow process) > > I would like to know is there any mechanism to understand > which rulebase > will be appropriate without executing the rule completely. > a mechanism such > as where we can compare the set of variable required by the > rule and set of > variable that i am passing for execution. this can be one > of the mechanism, > like that is there any other mechanism available with > drools. > > I hope i am clear enough, please let knw...if i need to be > more clear, it > will be very helpful...... > > Thank u all for the response..... > > Anstis, Michael (M.) wrote: > > > > Hi Nikhil, > > > > Let's break down what you have said into pseudo > Drools terms:- > > > > Rule 1 > > AdultFare(value==3000) > > ChildFare(value==2500) > > Then > > //Do what you want to do > > End > > > > Rule 2 > > ChildFare(value==2000) or > > InfantFare(value==1500) > > Then > > //Do what you want to do > > End > > > > Rule 3 > > AdultFare($f1 : value) > > InfantFare($f2 : value) > > eval($f1 + $f2 < 4000) > > Then > > //Do what you want to do > > End > > > > You suggest you have a RuleBase that has been > successfully loaded. > > > > You state you have some attributes (I assume these to > be implemented as > > Classes). > > > > StatefulSession ss = rulebase.newStatefulSession(); > > ss.insert( new AdultFare(1000) ); //<-- Causes > object to be compared > > to ALL rules.
