1. A deoxyribonucleic acid (DNA)-based data storage system, comprising:
a control system operable to:
identify a DNA strand for decoding, the DNA strand being associated with global parity information; and
a decoding system operable to:
separate the DNA strand into two or more short DNA strands; and
decode at least one short DNA strand of the two or more short DNA strands using local parity information that is unique to the at least one short DNA strand.
