aggregate data

Data that is the result of applying a process, such as combining data elements. It can also refer to data that is taken collectively or in summary form. Summary data, on the other hand, is aggregated according to specific criteria. For example, individual daily sales may be aggregated to weekly totals, or averaged to a single per/day number rather than maintaining all of the individual data elements.
