Data independence means
 

  • A.data is defined separately and not included in programs

  • B.programs are not dependent on the physical attributes of data

  • C.programs are not dependent on the logical attributes of data
  • D.both B and C

Answer: D

Correct answer: both B and C

Data independence has two halves: physical independence means programs do not depend on how the data is stored, and logical independence means they survive changes to the logical structure. Both are meant by the term, which is why the two options are taken together.
