Setting Column Properties on a Mining Structure

You can adjust the properties for a mining structure and for its associated columns and nested tables by using the Mining Structure tab of Data Mining Designer. Properties that you set in this tab are propagated to each mining model that is associated with the structure.

The following table describes the properties that are specific to data mining that you can view or configure in the Mining Structure tab for mining structures. To view or configure these properties, right-click an element in the tree view, for example a column or a nested table, and then click Properties.
