A 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.Attribute domains are rules that describe the legal values of a field type, providing a method for enforcing data integrity.
