Re: [rules-users] Re: Is this scenario suitable for using Drools?

without knowing how you are accessing the database your two algorithms come down to something like: Alg. 1 max(select max(p) from y, select max(t) from z) Alg. 2 select min(p) from y + select min(t) from z which is basically the same as what Michael has proposed. Personally I think if you are already using Drools then this would fit, but it wouldn't seem like enough of a reason to introduce Drools on its own. cheers Steve On Wed, Apr 23, 2008 at 2:27 AM, Cheng Wei Lee <zhenwei.li(a)gmail.com&gt; wrote: > I've 2 algorithms to calculate the cost of a product.
