For example, the data element “age of a person” with values consisting of all combinations
of 3 decimal digits; A personnel record may include the data elements “name” and “address”.
In the context of the personnel record, “name” and “address” function as an indivisible
unit, e.g., the data element “name” and the data element “address” each can be stored
and retrieved as an indivisible unit. However, in a different context, “address” itself
may be considered a record that contains its own data elements “street address”, “city”,
“postal code”, “country”.
