Methods, systems, and computer program products for monitoring, aggregating, and correlating business events in real time and acting on the results with near zero latency, wherein each event is processed in the first order relative to the event density, are described herein. In an embodiment, the method operates by receiving historical values comprising keys and data fields at an analytic model. Rules associated with actions are applied to the historical values. Actions including updating data are executed pursuant to the rules, and then the method determines whether additional rules are to be applied; and performs actions associated with these additional rules until there are no remaining rules to apply. The method stores updated data in a database.
