[rules-users] best practices for lookup tables like interest table?

[Greg Barton]

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

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
