What type of domain would you define to classify hurricanes by category?

The appropriate type of domain to classify hurricanes by category is a coded value domain. Coded value domains are used to assign specific coded values to a field, allowing for consistent categorization of data. In the case of classifying hurricanes, categories are typically predefined (such as Categories 1 through 5) and correspond to specific characteristics such as wind speed and damage potential.

Using a coded value domain enables the data model to maintain integrity and ensures that only valid categories can be assigned to each hurricane record. This structured approach is crucial for data analysis, as it facilitates reliable querying and reporting based on these defined categories.

Other types of domains such as range domains, string domains, or default domains do not serve the purpose of this specific categorization as effectively. A range domain defines a numeric range but is not applicable for discrete categories like hurricane classifications. A string domain is typically for text fields and would not provide the necessary coded framework for categorization. A default domain sets a value to be used when none is specified but does not assist in establishing a set of distinct categories for classification.
