Remarks

This enumeration describes the type of content represented by a mining structure column, and can be extended as needed by mining algorithm providers. For more information about content types, see Content Types (Data Mining).

The values listed in the following table are typically supported by all mining algorithm providers.

Value Description
Discrete The column contains discrete values.
Continuous The values for the column define a continuous set of numeric data.
Discretized The values in the column represent groups (or buckets) of values derived from a continuous column.
Ordered The values for the column define an ordered set.
Cyclical The values for the column define a cyclical ordered set.
Probability The values for the column specify a probability for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.
Variance The values for the column specify a variance for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.
StdDev The values for the column specify a standard deviation for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.
ProbabilityVariance The values for the column specify a probability variance for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.
ProbabilityStdDev The values for the column specify a probability standard deviation for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.
Support The values for the column specify support information for the column contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.

Note: This column is provided as part of the standard for third party mining algorithm providers. Microsoft provided algorithms do not make use of this column.
Key The column is a key column.

Note: This content type is applicable only to key columns, in which the IsKey element is set to True.

In addition to these standard values, mining algorithm providers included with Microsoft SQL Server Analysis Services support the values in the following table.

Value Description
Key Sequence The column is a key column, and the values for the column represent a sequence of events.

Note: This content type is applicable only to key columns, in which the IsKey element is set to True.
Key Time The column is a key column, and the values for the column represent time measurement units.

Note: This content type is applicable only to key columns, in which the IsKey element is set to True.
Sequence The values for the column represent a sequence of events.
Time The values for the column represent time measurement units.

The enumeration corresponding to the allowed values for Content in the Analysis Management Objects (AMO) object model is ScalarMiningStructureColumn.
