<p>PROBLEM TO BE SOLVED: To enable data before an update to be read out and reduce a necessary storage capacity.SOLUTION: A terminal device of an embodiment has a storage unit, a management unit, a detection unit, a reference giving unit, a reference deletion unit, a determination unit, a re-linking unit, and a deletion unit. Upon detecting that a graph element read out by a processing unit has been updated before its transaction starts, the terminal device re-links or deletes link information from an adjacent graph element of a graph element determined not to have given reference information by the determination unit, to a graph element after being atomically updated, and deletes a graph element for which all of link information has been re-linked or deleted and which is not given the reference information.</p> |
