たことを特徴とするデータフアイル管理装置。[Claims for Utility Model Registration] In a multi-program system in which a data file on an auxiliary storage device is accessed by any program on the main storage device, a data file buffer device that temporarily stores file data read from the auxiliary storage device. and,
a data file buffer management device that manages the usage status of the buffer; a parameter input device that inputs instruction information regarding access based on a data file access request on the auxiliary storage device from the program on the main storage device; a file access determination device that determines whether to access the file data from the auxiliary storage device or from the data file buffer device based on instruction information input by the user and management information in the data file buffer management device; Further, by incorporating a data file reading device and a data file writing device that perform data access with the auxiliary storage device or the data file buffer device in response to an access instruction from the discrimination device, the main storage device To reduce the number of accesses to the auxiliary storage device whose access time is significantly slow compared to that of the auxiliary storage device, thereby reducing processing delays due to access to the auxiliary storage device, and to allow multiple programs to simultaneously access the same data file on the auxiliary storage device. A data file management device characterized in that the data file management device sometimes discriminates the type of access and allows the same access if there is no problem in processing.
