Re: [rules-users] How to use KnowledgeBase

Hi, In theory, you can do it both ways. Depending on your situation, you will have to assess which approach will be the best solution. Regarding the fact that creation of a kbase takes some time, you will probably want to avoid doing it multiple times per transaction or, at least, cache them. Also, when your rules are part of a continupus flow, you probably want only 1 kbase. In your situation, mortgages, I assume your rules are following eachother with no or very little interaction from the user. In that case, I think one would normally use 1 knowledgebase. Theoretically, multiple knowledgebases should be used when dealing with completely different rulesets, with one ruleset not influencing the other (or execution of ruleset one happening in a totally different timeframe as to justify the use of another kbase). I hope this makes it clear.
