The logical data specification contains generic settings for the fields to be used for a training run. It does not include data from your source tables. The logical data specification is independent of the data mining function that you are using.
Defining the logical data specification is the next step in the model-building process. In this step, you create values of the data type DM_LogicalDataSpec, perform operations on them, or both.
Intelligent Miner® can create a default logical data specification from the input data definition. You can modify the default logical data specification or you can write your own. For example, you might want to create generic data mining settings. Generic field definitions and settings are independent of physical data. This means that you can use these generic data mining settings for different source tables with different layouts but with similar content. For example, you might want to use different sources for a customer segmentation with the Clustering mining function.
The logical data specification can also contain name mappings or taxonomies.
