<p>A computer capable of managing reference relationships between data executes access of first and second storage regions in which stored data can be altered and a third storage region in which stored data cannot be altered. The computer sets specification data in the first storage region for accessing data stored in the second and third storage regions, and shifts data having a reference relationship with the specification data from among the data stored in the third storage region to the second storage region. If the accessing occurs while the shifting is being carried out and the data has already been shifted to the second storage region, the reference information for the specification data is amended to the shifted location of the data, and all of the references to data in the third storage region that are referenced by the specification data are amended, thereby releasing the third storage region.</p> |
