“Temporal data” is data that varies based on time.Temporal data can retrieved from the database given a timestamp. The database query would return the data as it existed, or will exist in the future, at the indicated time.
As-of-date circumstancing is an example of temporal data in the form of a rule examined by Pega’s rule engine.
Regular non-rule data can also be temporal.
As opposed to extending Rule-, a simpler base class can be used for regular data that is temporal in nature.
A price list is an example of temporal data. Prices can remain fixed for a year a time after which they are increased by some factor.
