Drrols 5 Expert --> Sequential vs Inference

[Vijay K Pandey <VP...@mdes.ms.gov>]

Hi,



We have around 3500 business rules and rules are mainly look up value based or based on the associated data in the RDBMS.



There are around 90% processes where we only need sequential rules check, the other 10% of processes requires the inference capability.



My questions:



a)    Which is the best way to go for this - should we set up all the rules as inference through stateful session or segregate 90% as sequential and others as inference. Will this segregation going to give better performance in Drools 5 and later?



b)    Lots of our LHS depends on the data from RDBMS - we insert 1 fact - then make use of "from/collect" to get hold of various associated data ---then do some checks on the data fetched from RDBMS -- so is it better to program them in java directly or as sequential rules?



Any guidance will be helpful?



Thanks

Vijay
