ABSTRACT:
A method and system generate a compacted binary coded decimal (BCD) data set from a BCD digital data stream. The invention uses a translation matrix to translate blocks of data extracted from the BCD digital data stream. The BCD blocks are read to determine the number and position of 1's or 0's in the BCD block. The invention then generates a unique identifier number from a set of identifiers associated with either each of the 1's or each of the 0's. The result is a BCD number that has fewer BCD digits than the original BCD block. This process may be repeated numerous times to result in a compacted BCD data set that has fewer BCD digits but that can be translated back to the original BCD blocks that form the original BCD data stream.
