# aggregation in data mining Solutions Just Right For You

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. Therefore Most data mining algorithms takes as input data set with a horizontal layout. Significant effort is required to prepare summary data set in a relational database with normalized tables. For preparing data sets suitable for data mining analysis from normalized tables, we have to write complex SQL queries, operation of joining tables and column aggregation. Horizontal aggregation can be
