Description

Shared aggregates compute the value of an entity attribute by aggregating values from events that are associated with the entity. You can access the value for any specified time. Shared aggregates can reduce the time to calculate a value from the history of past events because they can be used by multiple agents and at multiple time periods. You can use a shared aggregate to detect when a change in a value occurs over time.

This sample uses shared aggregates on train delays to make year-to year, month-to-month, and result-to-target comparisons.
