Add each entry in the table as a working memory object. Insert them in a rule that fires immediately at startup. declare LookupEntry days : int amount : int value : double end rule "Init Lookup" when then LookupEntry entry = new LookupEntry(); entry.setDays(30); entry.set(Amount(5000); entry.setValue(2.7); ...etc for all entries... end ----- Original Message ---- From: strug <strug(a)web.de&gt; To: rules-users(a)lists.jboss.org Sent: Mon, October 19, 2009 12:39:11 PM Subject: [rules-users] best practices for lookup tables like interest table? hi, i'm quiet new to writing rules and asking myself - ah you - what is the best way to implement a lookup table? i want to have the following table reachable from within my rules: | 30 days | 60 days | 90 days > 5000 € | 2.7 % | 2.8 % | 2.9 % > 10000 € | 2.85 % | 2.9 % | 2.95 % > 20000 € | 2.9 % | 2.95 % | 3.0 % .. is it best to write a function which works internally on a two dimensional array? i want to have the numbers/tables be part of the drl files, in order to be able to dynamically reload them, so a java helper class is not aimed. thanks for any feedback and experience, leif -- View this message in context: http://www.nabble.com/best-practices-for-lookup-tables-like-interest-tabl...
