Abstract
Aggregating data includes accepting a first data set that includes records, each record holding a value for each of a plurality of fields. A second data set is generated from the first data set. The second data set includes one or more aggregated records each corresponding to one or more records from the first data set that match values in a subset of fields. A third data set is generated from the second data set. The third data set includes one or more aggregated records each corresponding to one or more aggregated records of the first data set that match values in a subset of fields. An aggregate value associated with an aggregated record in the third data set represents a result of performing a non-cascadable operation on values associated with a plurality of records from the first data set.
