Value Sets (domain) of Attributes

Each attribute of an entity type is associated with a value set. This value set is also called domain. The domain of an attribute is the collection of all possible values an attribute can have.

The value set specifies the set of values that may be assigned for each individual entity. For example, we can specify the value set for designation attribute as <“PM”, “Assit”, “DM”, “SE”>. We can specify “Name” attribute value set as <strings of alphabetic characters separated by blank characters>. The domain of Name is a character string.
