(2) Operation Next, the operation of the above embodiment will be described.

Slip Issuance Processing First, the operation for issuing a sales slip of a product or totaling will be described. When performing the above processing, first, the PS corresponding to the processing, that is, PS1 is input device.
10 is specified, and the specified signal is
Give to. The edit processing device 11 reads out the tables A to E of PS1 from the PS file 12 based on the above specification, loads them into the word memories 13 to 18, and gives a start command to the input processing device 19. This activates the input processing device 19,
The input processing shown in the flowchart of FIG. 4 is executed.

That is, the input processing device 19 checks the presence or absence of the start command in step A1, and the edit processing device
When a start command is given from 11, an input guide for data corresponding to a keyword name or an updated word name is provided based on Table A stored in the input word memory 13. The operator sequentially inputs data corresponding to the keyword name of “product code” and the updated word names of “quantity, unit price, and amount” from the input device 10 according to the input guide (step S1).
A2). The input processing device 19 processes the data input from the input device 10, and sequentially writes the data into the work memory 26 as word data corresponding to each word name (step A3). Next, in step A4, it is determined whether or not the end designation key for instructing the end of data input for one slip has been operated on the input device 10, and if not, the process returns to step A2 to repeat the same processing. When the end designation key is operated,
The input processing device 19 outputs a start command to the file creation device 21 (step A5). Thereafter, the input processing device 19 returns to step A1 and prepares for the next start command.

The file creation device 21 is started by a start command from the input processing device 19, and creates a maintenance record for file update according to the flowchart of FIG. That is, the file creation device 21 determines whether or not there is a start command in step B1 of FIG. 5, and when a start command is given from the input processing device 19, first, a CA table that defines real collation with respect to the master file 29 is set. Is set in the real input word memory 15a (step B).
2) If the CA table is not set, it is further determined whether or not the C table defining the batch update is set in the file word memory 16 (step B3). If table C is not set, the process returns to step B1 without performing any processing. In this case, since there is a C table, the first record data of a plurality of record data composed of word data written in the work memory 26 by the input processing device 19 is designated (step B4), and FIG. Based on the table C of c), for example, as shown in FIG. 6, creation of maintenance record data for file update including data indicating a file name, a keyword name, an update word name and a code indicating an update type in one record. The process is performed and registered in the maintenance file 27 (steps B5 and B6). Thereafter, it is determined whether or not maintenance record data creation processing has been completed for all record data held in the work memory 26 (step B7). If not completed, the next record data is designated (step B8). Returning to step B5, the same processing is repeated. Thereafter, if it is determined in step B7 that the processing for all record data has been completed, the process returns to step B1 to prepare for the next start command.

As described above, the file processing device 21 sequentially creates maintenance record data based on the word data stored in the work memory 26, and sequentially registers the created maintenance record data in the maintenance file 27. The above registration is performed every time each slip is issued. As a result, the maintenance file 27 registers all the maintenance record data created with the issuance of a plurality of slips. Then, after that, the input device 10 gives the file update device 28 an update command for executing an update process for batch processing, so that the file update device 28 is activated. When the update command for batch processing is given, the file update device 28 sequentially reads the maintenance record data registered in the maintenance file 27, and based on the data of the file name of each maintenance record data, The “sales file” is designated, and the update process of “total” is performed by the word data corresponding to the keyword name and the updated word name based on the update type code.

As described above, according to the data processing apparatus of the present embodiment, when issuing a slip at the time of sales of a product, a PS that defines that an update process for a file is to be performed is set in advance, and a file can be set at any time. , The files can be updated collectively later without affecting the processing speed when issuing the slip. In addition, as processing inside the apparatus, there are input processing of data corresponding to the word name (processing in the input processing apparatus 19) and processing of creating maintenance record data that allows a file to be updated later based on the input data. (The processing in the file creation device 21) is completely separated, so that the definition setting for each of the above processings is simple. That is, as the definition of the PS, it is only necessary to define the input definition of the update data (Table A) and the update definition for the file (Table C) using parameters such as word names, so that the definition setting is very simple. .

By the way, even in the above-described apparatus configured to perform an update process on a file, the content of the file is searched and read out on a display screen, and the read out content is checked, and then the corresponding file is checked. For example, there may be a case where the user wants to update a stock file or the like. Therefore, the data processing device of the present embodiment can perform the file search process using the configuration as it is.

File Retrieval Processing Next, a description will be given of an example of processing in a case where a product is checked out after the product is stocked. When performing the above processing, first, the PS corresponding to the processing, that is, PS4 is designated by the input device 10, and the designation signal is supplied to the edit processing device 11. The edit processing device 11 reads out the tables A to E of PS4 from the PS file 12 based on the above specification,
The table A shown in FIG. 3B is stored in the input word memory 13,
The table B shown in FIG. 3C is stored in the processed word memory 14, the CA table shown in FIG. 3D is stored in the real input word memory 15a, and the CB table shown in FIG. 3E is stored in the real processed word memory 15b. At the same time, the table D and the table E are loaded into the display word memory 17 and the print word memory 18, respectively. After that, a start command is given to the input processing device 19. As a result, the input processing device 19 is activated, and prepares for data input from the input device 10.

When a start command is given, the input processing device 19 performs the input process shown in the flowchart of FIG. That is, the input processing device 19 stores the input word memory 13
The data corresponding to the keyword name or the updated word name is input based on the table A stored in. At this time, the keyword name is “product code” and the update word name is “stock quantity”, so the operator inputs product code data “= 11” for “watch”, for example, as the product of the inventory inquiry, Subsequently, “≧ 100” (100 or more) is input from the input device 10 as inventory quantity data. When the data input based on the table A is performed, the input processing device 19 writes the input product code data “= 11” and the stock quantity data “≧ 100” into the work memory 25 (the seventh item).
Then, the file creation device 21 is started.

Upon receiving a start command from the input processing device 19, the file creation device 21 performs the maintenance record creation process shown in the flowchart of FIG. At this time, since the CA table is set in the real input word memory 14, YES is determined in the step B2, and the real process shown in FIG. 8 is executed (step B9). First, the eighth
At step C1 in the figure, it is determined whether the processing has been performed on Table A or the processing on Table B. At this point, since the processing of Table A has been performed, the process proceeds to Step C2, where the keyword data “= 11” and the updated word data “≧ 100” are read from the work memory 26, and are stored in the CA table of FIG. On the basis of,
The maintenance record data for file update as shown in FIG. 7 (3) is created and registered in the maintenance file 27. Thereafter, the file update device 28 is instructed to start the update process for the real process (step C3), and the process of step B9 in FIG. 5 is completed, and the process returns to step B1.

The file update device 28 executes the file update process shown in the flowchart of FIG. 9 in response to a start command for real processing from the file creation device 21. That is,
The file update device 28 checks in step D1 whether or not there is a start command for real processing, and when a start command is given from the file creation device 21, the file update device 28 includes the start command in the maintenance record data registered in the maintenance file 27. Specify the “stock file” in the master file 29 based on the data of the file name (step
D2) and the code of the update type are determined (step D)
3). The code of the update type in the CA table is "range collation". In this case, the process proceeds to step D4, where the upper two digits of the product code data in the record data stored in the "stock file" are "11". (Keyword data)
The record data is searched, and it is further determined whether or not the stock quantity data is “100 or more” (update word data) for the searched record data (step D5). If satisfied, the data is registered in the work memory 30 (step D5). Step D6). After that, it is determined whether or not all record searches have been completed,
If not, the process returns to step D4 to perform the next search. Thereafter, inventory products matching the keyword data and the updated word data are searched by the same processing, sequentially registered in the work memory 30, and the registered contents are transferred to the display processing table 22 and displayed on the screen. In this case, the top 2 of the product code
The digits indicate the product category, and the product code whose upper two digits are “11” indicates the category of “clock”. Therefore, "Watch A" (= 111011), "Watch C" (= 111013),
"Clock A" (= 111021), "Clock B" (= 1102)
All product codes such as 2) are searched, and the search answer is displayed on the screen. Then, upon ending the above-described record search, the file update device 28 starts the processing device 20 (step D8), and thereafter returns to step D1 to prepare for the next start command.

When the start command is given from the file updating device 28, the processing device 20 reads out the table B from the processing word memory 14 and inputs it to the input processing device 19. This input processing device 19
Accepts the input of "number of orders" in accordance with the above table B.

In accordance with this, the operator inputs the order quantity data for each product from the input device 10, for example, the order quantity data "100" for the product code "11011" and the order quantity data "50" for the product code "11022". . Then, the input device 19 is
The key input data of the number of orders is written into the work memory 26 as shown in FIG. 7 (3) (steps A2 and A in FIG. 4).
3). Then, when an instruction indicating that the input of the number of orders for all the products to be ordered is completed is given from the input device 10, the input processing device 19 gives a start command for real processing to the file creating device 21. (Steps A4 and A5), and returns to Step A1.

The file creation device 21 re-executes the process of step B9 in FIG. 5, that is, the process of creating the maintenance record in the real process as shown in FIG. 8, in response to the start command for the real process. At this point, since the processing of the table B has been performed. Step C1 to Step
Proceeding to C4, work memory 26 created based on Table B above
Is specified, and a record area for maintenance is prepared in the file creation device 21 (step C5). Thereafter, the keyword data and the updated word data of the record designated in step C4 are read from the work memory 26, and the read word data (product code = 111011, stock quantity = 100) is referred to as "file name (stock file)". ”And“ type (calculation) ”in the maintenance record area (step C
6). Then, the data set in the maintenance record area is registered as one maintenance record data in the maintenance file 27 (step C7), and it is determined whether or not the processing for all the record data created in the table B has been completed. (Step C8). If not completed, another record data created in the table B is designated, and the process returns to step C5 to perform maintenance record data creation processing. In this case, since other record data remains in the work memory 26, the record data (the product code is “11022” and the stock quantity is “50”
Is read and registered in the maintenance file 27. When the processing for all records created in the table B is completed, maintenance record data as shown in FIG. 7 (4) is stored in the maintenance file 27, and the file updating apparatus 28 is activated for real processing. A command is given (step C3), and the process of step B9 in FIG. 5 ends, and the process returns to step B1.

The file update device 28 executes the processing shown in FIG. 9 in response to the start command. That is, when a start command for real processing is given, the file update device 28 reads “inventory” in the master file 29 based on the file name data included in the first maintenance record data stored in the maintenance file 27. The file is designated (step D2), and the update identification code is determined (step D3). The update type code in this case is
Since it is "aggregate", the process proceeds to step D9, where record data matching the keyword data included in the maintenance record data is searched from the "stock file".
A word operation (step D10) is performed on the searched updated word data of the record data using the updated word data of the maintenance record data. In this case, the keyword data is “1101” from the “stock file”.
The record data of "1" (watch A) is searched, and the updated word data, that is, the stock quantity data "450" is totaled with the order quantity data "-100" of the maintenance record data. Then, it is determined whether or not the totaling result (450−100 = 350) is negative (step D11). If not, the record data after calculation, that is, the keyword data is “1101”.
At "1", record data whose update word data is "350" is temporarily registered in the work memory 30 (step D12). After that, it is determined whether or not the aggregation processing using all the maintenance record data stored in the maintenance file 27 has been completed (step D13). If not completed, another maintenance record data is designated (step D14). Returning to step D9, the same processing as above is performed. That is, in this case, the record data whose keyword data is “11022” (clock 13) is searched from the “stock file”, and the updated word data, that is, the order number data of the maintenance record data “160” is obtained from the stock number data “160”. −50 ”and the result of this calculation (160−50 = 110)
Is determined to be negative, and if not negative, the record data after aggregation, that is, the record data in which the keyword data is “1102” and the update word data is “110” is stored in the work memory 3.
Register to 0 temporarily. And maintenance file 2
When the totaling process using all the maintenance record data in 7 is completed, the record data of the same keyword in the “stock file” is corrected by each record data stored in the work memory 30 (step D15). In the present example, the stock quantity data of "watch A" is corrected to "350" and the stock quantity data of "clock B" is corrected to "110".

Thus, the file update process ends, and the process returns to step D1 to prepare for the next update start. If the counting result is determined to be negative in step D11, that is, if the stock quantity data is smaller than the order quantity data, the tabulated record data temporarily registered in the work memory 30 is used. (Step D16), and outputs an NG signal to the display processing device 22 (Step D17) to display a message such as "Something could not be updated."
The process returns to step D1 to prepare for the next update process.

As described above, according to the data processing device of the present embodiment, it is defined that the file search process should be performed prior to the file update even if the device is configured to have the optimum configuration for performing the file update process. If the PS is set in advance, the contents of the file can be checked immediately or the file can be immediately updated based on the input of the update data. In addition, the definition of the PS also includes the search condition input definition (Table A) and update data input definition (Table B), and the file search definition (CA table) and update definition (CB table).
Need only be input and defined using parameters such as a word name, and the definition setting is very simple.

In the above-described embodiment of issuing a slip, the file creation device 21 starts processing after the word data for one slip is stored in the work memory 26, but the data for one record is stored. The processing may be started later, or the word data for a plurality of slips may be stored. In other words, regardless of the amount of data stored in the work memory 26, the file creation device twenty one
May be performed independently. Further, the file updating device 28 starts the process after all the maintenance records are written in the maintenance file 27. However, the file updating device 28 may perform the process every time one maintenance record is written. The processing may be started after the maintenance record for the slip is written.

[Effects of the Invention] According to the present invention, a search process for querying a file to be queried based on a file query definition prepared in advance and query condition data input according to the definition is performed by a file update definition and its definition. Can be realized in exactly the same mechanism as the update processing mechanism for updating the data of the file to be updated based on the update data input according to the above. By the file definition, a series of processes such as a data inquiry from the inquiry target file and a data update based on the inquiry data can be quickly performed.
