屬性值

A string that contains the content of the column in the ScalarMiningStructureColumn object.

備註

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 內容類型 (資料採礦).

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 (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 ClassifiedColumns.

Variance

The values for the column specify a variance for the columns contained in ClassifiedColumns.

StdDev

The values for the column specify a standard deviation for the columns contained in ClassifiedColumns.

ProbabilityVariance

The values for the column specify a probability variance for the columns contained in ClassifiedColumns.

ProbabilityStdDev

The values for the column specify a probability standard deviation for the columns contained in ClassifiedColumns.

Support

The values for the column specify support information for the column contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn.

附註：

This column is provided as part of the standard for third party mining algorithm providers.

Note  Algorithms provided by Microsoft do not have any use for this column..

Key

The column is a key column.

附註：

This content type is applicable only to key columns in which IsKey is set to true.

In addition to these standard values, mining algorithm providers included with Microsoft SQL Server 2005 Analysis Services (SSAS) 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.

附註：

This content type is applicable only to key columns in which the IsKey is set to true.

Key Time

The column is a key column, and the values for the column represent time measurement units.

附註：

This content type is applicable only to key columns in which the IsKey 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.
