Abstract

PURPOSE:To attain a correcting job quickly with reduced labor by correcting the data having errors out of a large quantity of data already stored based on the discrimination data while discriminating those data having errors. CONSTITUTION:The input data is stored in the 1st storing means 2 and at the same time a detecting means 1 detects whether the input data has an error or not. If an error is detected, the means 1 delivers the data discriminating information and the error type information corresponding to the relevant data. These information are stored in the 2nd storing means 3. Then the means 3 is retrieved based on the error type designation output given from an error type designating means 4. The data discriminating information corresponding to said error type designating output is delivered from a retrieving means 5. Then the data corresponding to the data discriminating information is extracted out of the means 2. The desired correction is given to said extracted data from a correcting means 6 and sent back to the means 2.

Description

[Detailed Description of the Invention] [Summary] While or after performing identification processing on data with errors among a large amount of input data,
To reduce labor and quickly correct data in which an error has occurred among a large amount of data already stored, based on identification data.

[Industrial application field]

The present invention relates to a data input method, and more specifically, to a data input method that can easily and quickly correct error data that occurs in a large amount of input data.

It is important for the data to be input to the data processing device without errors in order to make the processing results meaningful. There is a man-machine interface in the input data system to the data processing device, especially data processing on the human side involved in that interface, so even if no errors occur on the machine side, , there is an unavoidable possibility that errors in data that are generated artificially may occur. It is also necessary to be able to correct such errors.

[Conventional technology]

Conventionally, in order to completely eliminate the above-mentioned errors and completely maintain the reliability of data in data input, the work has been carried out exclusively manually, with a great deal of effort. Difficult problems encountered with such techniques arise when the initial creator of the data and the person inputting the data into the computer are different people.

[Problem that the invention seeks to solve]

That is, if an error is discovered in the data, a situation may arise in which it is not possible to contact the data creator at that time. In such cases, it is inevitable that after a considerable amount of time (for example, several days) has passed, the data creator will be provided with a mechanically printed list showing the details of the error and which input record the error has occurred in. etc. will be notified.

However, if correction work is to be performed based on the above notification, it is necessary to indicate which record is in error and then correct the error, so it is necessary to notify the user that there is an error on the spot at the time of input. It is unavoidable that this method becomes more troublesome as it involves the work of specifying each record one by one.

Furthermore, it is difficult to monitor data such as what percentage and type of errors occur in the input data, whether there are many or few errors, etc. from the above-mentioned list.

Therefore, there is a risk that corrections will not be made promptly and that it will not be possible to know when reliable data will be completed.

The present invention was created in view of the above-mentioned problems, and is a data system that automatically detects erroneous data in a large amount of input data and corrects the erroneous data by specifying the error type. The purpose is to provide an input method.

[Means for solving problems]

FIG. 1 shows a block diagram of the principle of the present invention. In this figure, numeral 1 is a detection means that outputs data identification information and error type information when there is an error in input data, and 2 is a first storage means that accumulates input data. 3 is a second storage means for storing data identification information and error type information from the detection means 1; 4 is an error type designation means; 5 is a search means for searching the second storage means in response to the error type designation output from the error type designation means 4 and outputting data identification information corresponding to the error type designation output; be. Reference numeral 6 denotes a modification means that obtains data corresponding to the data identification information from the search means 5 from the first storage means 2, modifies the data, and returns the data to the first storage means 2.

[Effect]

While the input data is stored in the first storage means 1, the detection means 1 detects whether or not there is an error in the input data. If there is an error, data identification information and error type information corresponding to the data are output from the detection means 1, and these information are stored in the second storage means 3.

Thereafter, the second storage means 3 is searched based on the error type designation output from the error type designation means 4, and data identification information corresponding to the error type designation output is output from the search means 5. The data corresponding to this data identification information is retrieved from the first storage means 2, the necessary corrections are made by the modification means 6, and the data is returned to the first storage means 2.

In this way, errors in data can be detected automatically and at high speed, and data can be corrected without requiring a correction operator to specify data identification information for each item.

〔Example〕

FIG. 2 shows an embodiment of the invention. In this figure, 1
0 is an input card, which is one of the information media on which data (records) to be input are recorded, but other information media such as a magnetic tape may be used.

Reference numeral 20 denotes a card reading device which reads the card and sends the data recorded thereon to the error detection means 30 and the data storage means 40.

The error detection means 30 is, for example, a general-purpose computer system, and its function is to detect the number of the record with an error (record identification information) based on the content of the data itself or the mutual comparison of the content with other data. This is to detect the error type information. The types of errors are classified, for example, depending on which position on one record is incorrect. Detected errors may then be used in the conventional manner to add appropriate messages to a mechanically printed checklist displaying the input.

50 and 60 are a record level buffer and an error type buffer, respectively, which are used to transfer the record identification information and error type information detected by the error detection means 30 to the error information storage means 70. The error information storage means 70 may be an information storage unit called one file within the computer system, for example.

Reference numeral 80 denotes an error search means for extracting the corresponding record identification information from the error information storage means 70 in accordance with the error type indication output signal of the error type indication means 90. 100 is a record identification information buffer that temporarily holds the retrieved record identification information.

Reference numeral 110 denotes a correction target search means, which searches the data N product means 40 for a record (data) corresponding to the information in response to the record identification information from the buffer 100, retrieves it, and sends it to the display correction/editing means 120. It is something to send.

The output record of the display correction/editing means 120 is stored in the corresponding storage area of the data storage means 40 via the correction data storage means 130.

The operation of the present invention configured as described above will be explained below.

The records (data) read by the card reading device 20 are stored in the data storage means 40, and
The error detection means 30 checks whether there is an error, and if there is an error, the record identification information (record failure) is detected.
and error identification information are output and stored in the error information storage means 70 via buffers 50 and 60.

By performing such storage, the error search means 80 can retrieve the record identification information of the record having the error type information specified by the error type instruction signal outputted from the error type indication means 90 whenever desired. The information is searched and output from the information storage means 70. The processing by the error search means 80 does not require complicated and time-consuming processing such as error determination, and only needs to be determined whether or not there is error type information with the same contents as the instructed error type information. , can be processed very quickly.

The record identification information output from the error search means 80 is given to the correction target search means 110 via the buffer 100. The correction target search means 110 uses the given record identification information? [The corresponding record is retrieved from the data storage means and displayed on the display screen of the display correction/editing means 120, and the record is corrected to the correct record through its correction/editing function. Thereafter, the corrected record is sent to the corrected data storage means 130, and a record with correct contents is stored in the data storage means 40 in place of the erroneous record retrieved as described above.

Furthermore, once one record has been corrected as described above, the next record with an error is searched for and the same process as described above is automatically repeated.

In the above embodiment, an example was explained in which the record identification information is directly provided to the correction target search means 110.
It is also possible to create error statistical information by counting the number of records for each error type, or furthermore, by combining these and displaying the error statistical information on the display screen,
It is also possible to automatically search for correction records sequentially as described above for the error type specified on the screen.

Furthermore, the input data supplied to the error detection means 30 and the data storage means 40 may be from a communication line.

Further, in the above embodiment, the error search means 80 searches and outputs the record identification information from the error information storage means 70 using only the error type information. It can also be used in conjunction with type information to perform a similar search output based on error type information for a specific person or period.

〔Effect of the invention〕

As explained above, according to the present invention, errors in data can be detected automatically and at high speed, and data can be corrected without requiring a correction operator to specify data identification information for each item. In other words, quick correction work can be performed with less effort. Furthermore, the status of input data can be grasped in a timely manner in order to manage data reliability.
