Data Types (DMX)
When you use Data Mining Extensions (DMX) to define a new mining model in Microsoft SQL Server Analysis Services, you must provide a data type for each column in the model. The data type describes the data that the data mining algorithm will use when it builds the model.
Data types depend on the algorithm. Each algorithm determines which data types are supported and how they are used. Microsoft algorithms support the following data types:
