An overview of the Domains toolset

Domains offer a way to define a range of values that can be used for multiple attribute fields. Using domains helps ensure data integrity by limiting the choice of values for a particular field. Validation for coded value domains is accomplished by restricting field values found in drop-down lists. Range domains are automatically validated during editing.

This table summarizes tools in the Domains toolset.
