Re: [rules-users] In drools what is the exact difference between Insert and Update ??

Far much valuable reply than mine :) A great summary of common concerns that must be evaluated before starting coding a rule system. Also consider : - using rule flow (if you are allowed to) - use sequential mode and pipe your data 'in the next rule box' programmatically (using rules?) - ask your architect ? He is true for no-loop, but for others, re-writing existing DRL code that used all that stuff, and throw all at once is farly more dangerous ... This is all the question. It mainly depends of the usage, as Davide said. It also depends of who is authoring/specifying rules : if the guy supposes some flow, he is not writing independant rules ... these other rules depend of the first : 2.no drools functions 3.Activation group / ruleflow / salience ... 5.don't call any java function (thus no functions at all, no predicates/utils methods, only DSL? only POJO?). this one is suspect ... 4.Don't use UPDATE and Global in drools .
