Attribute domains and subtypes


Two of the greatest concerns to most organizations are data integrity and efficiency during management, display, and editing operations. Domains and Subtypes tools offer a way to organize your data so that certain operations, such as editing, become more efficient while the integrity of the attributes is maintained.

Subtypes are a way to group features of one feature class into subsets based on an attribute value. In the example below, the Streets feature class is divided into two subtypes that are based on the value of the CLASS attribute field on the feature class table.

Using subtypes with domains

A attribute domain is a declaration of acceptable attribute values. Whenever a domain is associated with an attribute field, only the values within that domain are valid for the field. In other words, the field will not accept a value that is not in that domain.
