1. An online transactional data processing system, comprising:

  • a relational database for storing transactional data;

    an OLTP application program for processing the transactional data, the OLTP application program operable to generate a set of change documents for each run of the OLTP application program, wherein each change document is descriptive of a transformation of the transactional data;

    a mass storage device for storing the change documents;

    means for receiving a request for correction of a previous run of the OLTP application program;

    means for reading the set of change documents of the previous run from the mass storage device into a random access memory;

    means for inverting the transformations as described by the set of change documents of the previous run;

    means for initiating a renewed run of the OLTP application program to create a new set of change documents that are temporarily stored in the random access memory; and

    means for overwriting at least a sub-set of the set of change documents of the previous run stored on the mass storage device by at least a sub-set of the new set of new change documents.
