aggregation in data mining

Data mining – Aggregation

Aggregation for a range of values. When analyzing sales data, an important input into forecasts is the sales behavior in comparable earlier periods or in adjacent periods of time. The extent of such periods directly depends on the value in the time portion of the focus, because the periods are defined relatively to some point in time.

What is Data Aggregation?

Data aggregation is any process whereby data is gathered and expressed in a summary form. When data is aggregated, atomic data rows -- typically gathered from multiple sources -- are replaced with totals or summary statistics. Groups of observed aggregates are replaced with summary statistics based on those observations.
