Abstract
A data management method includes a reference activation step, after generating a first time-series data for causing chronological relationship to be identifiable in a memory device at activation of a reference operation to a first record in a database, of referring to the first record; an update step, in response to an update request for the first record, of generating a second record corresponding to the first record in the database and updating the second record; a commit step of generating a second time-series data in the memory device at a commit operation for the updating; a reference termination step of deleting the first time-series data at completion of the reference operation; and a deletion step, if the first time-series data generated earlier than the second time-series data is not present as a result of the commit step or the reference termination step, of deleting the first record.
