ABSTRACT:
A system (10) for compressing and decompressing records includes a decompressed file (12) and a compressed file (14). A first record is stored in a first buffer (18) and a second record is stored in a second buffer (20). A vertical compression technique compares the first record and the second record, on a field-by-field basis, and replaces the field of the second record with a vertical repeat indicator if the field of the second record matches the corresponding field of the first record. A horizontal compression technique further compresses the second record by replacing adjacent matching characters with a horizontal repeat indicator.
