Not trying to reverse engineer, but simply trying to grasp Oracle's equivalent to Interbase's "DOMAIN". A "DOMAIN", such as in Interbase or in CASE tools like Embarcedero's ERStudio, describe commonly used data types with certain constraints. This way you define the constraint once, then simply bind it to a given field.

Not primary key, just a field having boolean choices. Other examples of likely domains are

	"POSTAL_CODE_DOMAIN"
	"GENDER_DOMAIN"
	"ADDRESS_DOMAIN"
