    • 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.
    • 数据管理方法包括参考激活步骤,在参照第一记录产生第一时间序列数据之后,在激活对数据库中的第一记录的参考操作时,使存储器装置中的时间关系可识别; 更新步骤,响应于对所述第一记录的更新请求,生成与所述数据库中的所述第一记录相对应的第二记录,并更新所述第二记录; 提交步骤,用于在所述更新的提交操作中在所述存储器设备中生成第二时间序列数据; 参考终止步骤,在完成参考操作时删除第一时间序列数据; 以及删除步骤,如果作为提交步骤或参考终止步骤的结果,不早于第二时间序列数据生成的第一时间序列数据,则删除第一记录。
