  i) Key attribute  

  ii) Value set 

Key attribute:  An entity  type  usually  has  an attribute  whose  values  are  distinct  from every individual  entity in the collection. Such an attribute is called a key attribute. 

Value  set:  Every simple  attribute  of  an entity  type  is  associated with a  value  set that specifies the set  of values that might be assigned to that attribute for every individual entity.
