One of the great advantages of using the geodatabase to store geographic data is the ability to create subtypes for your features and attributes. Subtypes provide a method of dividing your feature classes or tables into logical groupings based on an attribute value. By allowing you to work with a subset of features in a feature class, subtypes make it possible to assign consistent attributes and behavior to those subsets.
