Abstract
In an update management apparatus, a detection unit detects an update of one or more kinds of data included in a data set stored in a storage unit. A management unit generates a symbol sequence including a plurality of symbols corresponding to the respective plural kinds of data, and stores the symbol sequence as information indicating a version of the data set. The management unit modifies the symbol sequence indicating the previous version to change a symbol Q1 to Q2, which corresponds to the kind of data whose update has been detected, out of the plurality of symbols, to generate a new symbol sequence indicating the updated version.
