Re: [rules-users] Collection in working memory!

Hi all, I'm new to Drools and have a simple question. In my program I have a collection A of objects B, and each B object has 30-40 attributes. And the rule run against these attributes of B. I want to run rules against each instance of B and I 've close to 45 rules. These rules can be grouped under 3 categories and at a time just 1 group need to be applied for a particular object....point is that there is no need to blindly run an object against all rules. Now with this background, I would love to hear what is the best implementation? I have put rules in 3 different DRL file and packaged them into single Rule base. For inserting the facts in working memory, I'm iterating through collection and inserting one B object at a time in Working memory and then firing all rules of any one group (for that I'm using RuleNameEndsWithAgendaFilter()). How bad is this design? Because I can see for 100 objects I'm inserting facts in working memory 100 times and then firing rules 100 times. I can make the top level collection 'A' global(or insert 'A' in WM) and then iterate over it from the rule file ...would that be a better solution? Would appreciate any input in this regard. Thanks.
