Claim 8:
9. The computer-implemented method of claim 1, the determining the one or more combinations of fields of the record further comprising:
determining, by one or more processing units, a plurality of combinations of fields of the record that satisfy the frequency criterion and a basic length criterion indicating that a length of each of the plurality of combinations of fields is not less than a basic length for the record;
calculating, by one or more processing units, a respective optimization ratio for each of the plurality of combinations of fields, the respective optimization ratio indicating a weighted compressed length of the record calculated based on the access of frequency of the combination of fields, a compressed length of the record, and a length of the record; and
selecting, by one or more processing units, the one or more combinations of fields from the plurality of combinations of fields that satisfy an optimization ratio criterion indicating that optimization ratios of the selected one or more combinations of fields are less than an optimization ratio threshold.
