A composite attribute is which of the following?

  • A.An attribute that can be broken into components
  • B.An attribute that cannot be broken into components
  • C.Multiple attributes
  • D.An identifier

Answer: A

Correct answer: An attribute that can be broken into components

A composite attribute has meaningful parts - an address into street, town and postcode, a name into forename and surname. Whether to store it whole or in parts is a design decision: split it if the parts will be used separately, and leave it whole if it will always be handled as a unit.
