Attribute domains are rules that describe the permissible values of a field type. Which geological components can they constrain? (Choose three.)

Attribute domains in GIS are designed to enforce data integrity by restricting the values that can be assigned to a field in a table or feature class. They can be applied to specific fields within different components of a geodatabase to maintain consistency and ensure that data adheres to defined standards.

The geological components that attribute domains can constrain include:

• Field: Domains are specifically applied to fields in a feature class or table to limit the type of values that can be entered. For example, a domain might specify that a particular field can only contain specific codes representing rock types, ensuring that the data collected is standardized.

• Subtype: Domains can also be applied to subtypes, which are a way of categorizing features within a feature class based on a shared attribute. This allows different sets of rules or permissible values to be associated with different subtypes, enhancing the granularity of data management.

• Feature class: A domain can be associated with a feature class to enforce constraints on the attributes of the entire class. This ensures that all features within the class adhere to the same set of rules regarding permissible attribute values.

Focusing on these components shows how attribute domains facilitate data accuracy and reliability in geological studies and GIS applications.
