The Subtypes toolset contains tools that create and edit subtypes, which provide a method of dividing feature classes or tables into logical groupings based on an attribute value.
One advantage of using a geodatabase to store geographic data is that you can create subtypes for features and attributes. When working with subsets of features in a feature class, you can use subtypes to assign consistent attributes and behavior to the subsets.
Adds a new subtype to the subtypes in the input table.
Removes a subtype from the input table using its code.
Sets the default value or code for the input table's subtype.
Defines the field in the input table or feature class that stores the subtype codes.
