Data Types (Data Mining)

Before you process a mining model in Microsoft SQL Server 2005 Analysis Services (SSAS), you can define the data types for the mining structure columns on which the model is based. Analysis Services supports the following data types for mining structure columns:

  • Text
  • Long
  • Boolean
  • Double
  • Date

Each of these data types supports one or more content types, which you can use to define column data even more. The following table identifies the content types that each data type supports. For more information about content types, see Content Types (Data Mining).
