[rules-users] How to Compute against WorkingMemory in Drools ?

I have been looking at the following scenario

1. Alerts are generated by an enterprise system and Sent to the Rule Engine
in batches.

2. I must check the alert batch for possible correlation between the alerts
based on Rules defined in my Rule file (.drl)

*3. Verify if any Correlation already exists for the alerts received if yes
update that correlation with fresh alert data*

4. if no correlation exists i do nothing.

5. If a Correlation exists and No correlation is present in RE representing
the same for those group of alerts I create a New Correlation and update the
RE.



*Steps 1 to 3 are repeated every 15 seconds in the system,*


How do I keep the Objects in Drools to keep checking for Correlation
scenarios as  and when I receive data from the enterprise system at regular
intervals so that i can update existing correlation as metioned at *Step 3*


Any approach or suggestion would be very helpful.
