Abstract

PURPOSE:To exactly execute the processing in case of recovery from cut-off of an electric power supply, and also to reduce a load of an updating processing device, by using a non-volatile memory having a high access speed and a small scale, for temporary saving, and storing file contents, etc. relating to updating. CONSTITUTION:When duplicate files FMA, FMB of a magnetic disk, etc. are updated bya data input means D, the processing is executed bya CPU of a data processing device DPU, a main storage device MM, etc. Subsequently, information related to updating such as a record before updating the updated place which has been saved temporarily from the files FMA, FMB, an advance stage of updating processing, an access state to the files FMA, FMB corresponding to unfinished updating and completed updating, etc. is stored in a non-volatile memory TM having a high speed and a small scale. Accordingly, a transaction file, etc. for updating become unnecessary, a load of an updating procesing device is reduced, a file is updated in high response, and also updatig processing after recovery from cut-off of an electric power supply is also executed swiftly and exactly in accordance with storage contents of the memory TM.
