Modeling Flags (Data Mining)

You can use modeling flags in Microsoft SQL Server 2005 Analysis Services (SSAS) to provide additional information to a data mining algorithm about the data that is defined in a case table. The algorithm can use this information to build a more accurate data mining model.

You can use the NOT NULL modeling flag with mining structure columns. This modeling flag indicates that the values for the column should never contain a null value, and that an error will result if Analysis Services encounters a null value for the column during the training process.

You can define additional modeling flags on the mining model column. For more information about defining these flags, see Mining Model Columns.

You can use Data Mining Extensions (DMX) to define modeling flags programmatically, or you can define them in Data Mining Designer in Business Intelligence Development Studio.
