Drools noob queries We are examining Drools for use in an insurance company. The scenario under consideration is underwriting rules. These rules are used in several processes e.g. quotes, adjustments, renewals etc. To help us in our assessment I was hoping you may be able to answer/provide guidance on the “noob” queries towards the end of this mail. For now we are looking at the Quotes process. Basically we’d like to replicate the existing process which goes something like this: 1. Check for minimum data requirements to complete process 2. Decide if data will cause an outright decline 3. Decide if data will cause an referral for human review 4. Calculate the premium required for a range of potential options that the end user will choose from i.e. we calculate several possible premiums The calculation process is pretty much a linear one. We never revisit any step once it has been passed through. In terms of execution the process is stateless. As part of the process there are look-ups to several large in memory collections. These collections would not change during execution. There may be several versions of the collections in memory at any one time (we could be supporting old and new rates at the same time and choose which to use based on a business date). Questions I’m assuming we can use Flow do dictate the execution process? Can we load the in memory collections and rules just once and keep this alive 24/7. We are mostly using thread safe singleton Spring beans in the rest of the app and we’re hoping a similar concept exists in Drools. What books would you recommend that would best suit our needs? -- View this message in context: http://n3.nabble.com/Drools-noob-queries-tp182561p182561.html Sent from the Drools - User mailing list archive at Nabble.com.
