Abstract

PURPOSE:To correct data even at the time of using a filing device and to efficiently correct data. CONSTITUTION:This method consists of the stage where the record key part of data to be corrected on the side of a terminal equipment 1 is stored in a storage medium, the stage where the storage medium is set to a host processor 2 and a record having the same key as the record key part stored in the storage medium is extracted from a filing device 211 and is stored in the storage medium, the stage where the storage medium is set to the terminal equipment 1 again and extracted data is displayed to correct a required part and corrected data is stored in the storage medium, and the stage where the storage medium is set to the host processor 2 and data in the filing device 211 having the same record key is substituted with corrected data of the storage medium.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data modification method for modifying data in a file device, and more particularly to a data modification method suitable for a system having a distributed input device configuration.

0002

2. Description of the Related Art Conventionally, as a method for modifying data in a file device in this type of system, there is a method in which, for example, when the file device is not in use, data is directly modified through an input device for the file. Another method is to create correction data on a medium from another data input device and then correct the data by replacing records when the file device is not in use.

0003

[Problems to be Solved by the Invention] In any conventional data modification method, it is difficult to modify data when the file device is being used for other processing. Also,
Regardless of the amount of data correction, it is necessary to create the data to be corrected anew, making the data correction work complicated.

The present invention has been made to solve these problems, and its purpose is to make it possible to modify data even when using a file device, and to efficiently perform data modification work. The purpose is to provide a data modification method.

[0005]

[Means for Solving the Problems] The present invention relates to a data modification method capable of solving the above-mentioned problems, and includes a process of storing a record key part of data to be modified on a terminal device side in a storage medium; Attached to the host processing device,
A process of extracting a record having a key that matches a key stored in a storage medium from a file device and storing it in the storage medium, and loading the storage medium into the terminal device again and displaying the extracted data to extract the necessary portion. The process includes the steps of modifying and storing the modified data in a storage medium, loading the storage medium into a host processing device, and replacing the data in the file device with the matching record key with the modified data in the storage medium.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of an information processing system used in the present invention.

In FIG. 1, reference numeral 1 indicates a plurality of terminal devices installed, and reference numeral 2 indicates a host processing device, which takes the form of distributed input. The terminal device 1 includes an input device 11 and an input/output device 12, and the input device 11 includes a display device 111 for displaying various types of information on a screen and a keyboard 112 for inputting data. Note that 121 is a floppy disk attached to the input/output device 12. The host processing device 2 also includes a storage unit 21,
The storage unit 21 includes an input/output device 22, and a file device 211 for storing data. In addition,
Floppy disk 121 attached to input/output device 22
is the same as that attached to the terminal device 1 side.

Next, the data correction method of this embodiment will be explained. First, the floppy disk 121 is attached to the input/output device 12 of the terminal device 1, and the record key part of the data to be modified is sequentially input using the keyboard 112. Thereafter, the input record key part using the input/output device 12 is outputted to the floppy disk 121, which is a data storage medium. Next, the floppy disk 121 storing this record key part is transferred to the host processing device 2.
set in the input/output device 22 of. Then, the host processing device 2 extracts from the file device 211 a record having a record that matches the key specified for modification, and outputs it to the floppy disk 121.

[0009] This floppy disk 121 is loaded into the terminal device 1 again, and the data previously extracted from the file device 211 is sequentially displayed on the display device 111. In this case, modify the necessary parts using the keyboard 112,
The corrected data is stored on the floppy disk 121 again. Thereafter, the floppy disk 121 containing the modified data is again attached to the input/output device 22 of the host processing device 2. Then, the data on the floppy disk 121 and the data on the file device 211 are read sequentially, and when the record keys match, the modified data is transferred to the file device 211.
Replace with the old data in 11. Through the above steps, data in the file device 211 can be modified. In this embodiment, for example, if the file device 211 is being used for other processing, the data in the file device 211 cannot be directly modified, but the data can be temporarily copied to a floppy disk as described above. This allows data to be modified at any time.

0010

As described above, according to the present invention, data in the file device can be corrected even when the file device is in use. Furthermore, there is no need to create the corrected data on a medium again, and only the corrected portions need to be input, which has the effect of allowing data to be corrected efficiently. Particularly when a large amount of data is to be modified, work efficiency can be improved by modifying the data in parallel using multiple input devices.
