Hi Earnie,<br><br>What you are explaining seems pretty straight forward and would more likely than not be overkill to use a rule engine. Are there other aspects of the system you are leaving out that warrant the use of Drools?<br>

<div><div style="font-family: tahoma,new york,times,serif; font-size: 10pt;">Greetings all,<br><br>I have a requirement to compare a set of facts against each other, calculate a value that indicates the amount of difference (Levenshtein distance) between a single attribute on each fact. So I load all of my facts into working memory then what? Do I execute a rule first that creates a new set of facts which is a Cartesian product of the original set of facts, each new fact containing a reference to two original facts and the diff between them? Looked at using a custom accumulate function but I don't think that's going to do what I need since it is intended to go through a set of facts and return a single value.<br>
<br>Any and all related help is appreciated.<br><br>Earnie! <br></div></div><br>_______________________________________________<br>
