Abstract

One embodiment relates to a computer-implemented method for generating difference data between reference and target files. A difference engine performs a first procedure to generate difference data representing the difference between the reference and target files if the reference and target files are sequences of sorted data records. The first procedure may compare a lexical order of a record from the reference file against a lexical order of a record from the target file. An entry may be added to a copy list if the records are the same, and an entry may be added to an add list if that the record from the reference file is lexically greater than the record from the target file. Another embodiment relates to an apparatus for generating difference data.
