Abstract

PURPOSE:To efficiently perform a processing to omit a time required for reconsideration of data by providing a history file where data before update is stored and using the data before update to perform code conversion. CONSTITUTION:A code file retrieving program means 1 receives input data as the object of code conversion to retrieve a code file 5; and if a code corresponding to input data cannot be retrieved, a history file 6 where data just before update is stored is retrieved to output the retrieval result. Next, a code file updating means 22 receives data for update of the code file 5 to update the code file 5 and a history file 6. Thus, the time required for reconsideration of data as the object of code conversion accompanied with update of the code file 5 is omitted.

Description

[Detailed description of the invention] [Industrial application field] INDUSTRIAL APPLICATION This invention is utilized for a file search in information processing.

The present invention relates to a code file search device using a history file.

〔overview〕

The present invention is a code file search device that searches a code file for a code of input data and performs code conversion. This is designed to improve processing efficiency and reduce the time required to review data.

[Conventional technology]

Conventionally, in this type of code file search, code conversion is performed when the data to be converted matches the data in the code file.

[Problem that the invention seeks to solve]

In the conventional code file search described above, after the code file data is updated, code conversion cannot be performed using the data before the update, resulting in unnecessary access to the code file and poor processing efficiency. , it also has the disadvantage of requiring time to review the data.

The present invention aims to eliminate such drawbacks, and provides a device that can access a history file that stores data before updating, improve processing efficiency, and eliminate the time required to review data. With the goal.

[Means for solving problems]

The present invention provides an input means for receiving input data that is a target of code conversion by providing a code file for storing data codes, a code file search means for receiving data obtained by the input means and searching the code file, and code file search program means including output means for outputting search results; update data input means for receiving data for updating the code file; and update data received by the update data input means for updating the code file. A code file search device is provided with a code file update program means that includes a code file update means for performing a code file update program. The present invention is characterized in that it includes a history file search means for searching the history file when the history file cannot be searched, and the code file update program means includes a history file update means for updating the history file.

[Effect]

The code file search program means receives input data to be converted, searches the code file, and when the code corresponding to the input data cannot be searched, searches the history file in which the data immediately before the update is stored. and output the search results.

Next, the code file update means receives data for updating the code file and updates the code file and the history file.

As a result, it is possible to omit the time required to review the data to be converted into the code when updating the code file.

〔Example〕

Next, an embodiment of the present invention configured as described above will be described based on the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment of the present invention is provided with a code file 5 for storing data codes, an input means 11 for receiving input data to be converted into a code, and a code for receiving data obtained by this input means 11 and searching the code file 5. Code file search program means 1 including file search means 12 and output means 14 for outputting search results;
Code file update program means including an update data input means 21 that receives data for updating the code file 5, and a code file update means 22 that receives the update data obtained by the update data input means 21 and updates the code file. 2, and further provided with a history file 6 for storing data before update, and the code file search program means 1 includes a history file for searching the history file 6 when the code file search means 12 is unable to search for data. A search means 13 is included, and a history file 6 is stored in the code file update program means 2.
It includes a history file update means 23 that performs zero update.

Figure 2 (a), (company), (C), (6), (eL (f
) and (ku) are diagrams showing the format of data.

Input data 3 is data used when searching a code file 5 or history file 6 as shown in FIG. This is the resulting data.

Further, the code files 5 are configured as shown in FIG. 6 (6), and are configured and stored in plural on a randomly accessible auxiliary storage device such as a magnetic disk device, for example.

The history file 6 is configured as shown in the figure (C), and a plurality of history files are stored on a randomly accessible auxiliary storage device such as a magnetic disk device, and the update data 7 is as shown in the figure (e). Update the configured code file.

Next, the operation of the embodiment of the present invention configured as described above will be explained. FIG. 3 is a flowchart showing the operation flow of the code file search program means 1 according to the embodiment of the present invention.

After inputting data, the code file search program means 1 performs code file search, code file search determination, history file search, history file search determination, each process, and unsearched process, and outputs data.

FIG. 4 is a flowchart showing the operation flow of the code file update program means 2 according to the embodiment of the present invention.

After inputting the update data, the code file update program means 2 performs processing of updating the code file and updating the right and history files.

First, when the code file search program means 1 is started, the data D6□ shown in FIG. 12 receives the field I from the manual means 11, uses the data D6□ of this field I as a search condition, accesses a code file as shown in FIG. 2(b), and searches for matching data (step 32). .

If no matching data is found, the history file search means 13 uses the data I)s2 of field I as a search condition to search for a history file 6 as shown in FIG. 2(C), for example.
and searches for data record RF2 having matching data (step 34).

Next, when matching data is retrieved, the code data C21 is set in the field ◯ as shown in FIG. 2 (6) via the output means 14. (Step 37).

Next, when the code file update program means 2 is started, the update data input means 21 inputs the data shown in FIG. 2(e) for updating the code file.
and data D 112 are input from field K (step 41). The code file update means 22 receives the field K from the update data input means 21, and uses the data C3I in the field as a search condition (for example, as shown in FIG. 2).
Access the code file as shown in , search for matching data, hold data record CF, update data D31 to field data I) sz, and enter the second
Create a code file as shown in Figure (f) (step 42).

The history file update means 23 receives the data record CF from the update data input means 21, and receives the data record CF from the update data input means 21, for example, as shown in FIG.
) (step 43).

〔Effect of the invention〕

As described above, according to the present invention, it is possible to omit the time required to review data to be subjected to code conversion when updating a code file.
