摘要: A data management apparatus and method provide for a virtual conversion by repeatedly reading at least one record from an input file having plurality of records, each including fields, adding the to buffer. The records in buffer are then converted into post-conversion block on field-by-field basis until size blocks kind field exceeds threshold size. number can be determined counting during process immediately preceding time when size, storing that number. is completed out stored file, converting read basis, blocks.
