Abstract
A replay method and system for monitoring the generating of a data set from input data sets and, when the data set is subsequently accessed, automatically regenerating the data set if the data set is out-of-date. The replay system only regenerates those input data sets that are determined to be out-of-date and only regenerates the output data set if it is determined to be out-of-date. A data set is determined to be out-of-date only when an input data set has actually changed since the data set was last generated.
