Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a data collecting apparatus according to an embodiment of the present invention.

In the figure, 1 is a spool file, which stores sales data of the day received from another CPU (computer) through a communication line or the like. A magnetic tape device (MT) 2 as an information resource records data such as slips.
3 is a floppy disk device (FD) as an information resource
The inventory management data and the like are recorded. Reference numeral 4 is a simulation file, which is a file in which a certain data sequence is created for simulating, that is, confirming the operation of the work. Reference numeral 5 denotes an option instruction file as conversion information storage means, which is a file in which code conversion data defining how to read and write data according to the data ID (identification information) as a reference parameter is stored. Incidentally, the data of the spool file 1, MT2, FD3, etc., has a corresponding data ID described therein.
Reference numeral 6 denotes an application data collection file (standby connection file), which is a set of subfiles in which data is stored in a unified format with a data ID as a file name. A data collection processing unit 7 collects data such as the spool file 1, MT2, and FD3, and reads the option instruction file 5 having the corresponding data ID. At this time, data having no corresponding data ID is transferred to the error file 8. When there is an option instruction, the data collection processing unit 7 performs a designated code conversion on the data to unify the data format, and sets the data in the application data collection file with the data ID as a subfile name.
Record as one subfile. Reference numeral 9 is a fetched data error list output processing unit, and contents of the error file 8 (error data) according to an error output instruction from the input unit 10.
Is displayed on the screen of the CRT 11. Further, the error list 12 is output as a form. Further, the fetched data error list output processing unit 9 deletes the contents of the error file 8 according to a deletion instruction from the input unit 10. A collection file maintenance processing unit 13 deletes the corresponding subfile in the application data collection file 6 according to a deletion instruction from the input unit 10. Further, the same processing as described above is performed according to the activation instruction from the application 14. 15
Is a simulation processing unit, and the simulation file 4
The test data is taken out from and the simulation subfile is created as one subfile in the application data collection file 6.

Next, the operation of this data collection device will be described.

In this data collecting device, when the sales data (text data etc.) of the day is received from another CPU through the communication line, the data is once dropped to the spool file 1.

When data exists in the spool file 1, the data collection processing section 7 confirms the option instruction based on the data ID added to the data.

In this case, the data collection processing unit 7 reads the data ID of the option instruction file 5 and determines whether or not it matches the data ID of the data of the spool file 1.

If the data IDs match, it means that the option instruction has been given. In this case, the data is code-converted based on the code conversion data that defines how to read and write the data corresponding to the data ID of the option instruction file 5, and the format is standardized, and then the data ID is set. The sub file name is recorded as one sub file of the application data collection file 6. The contents of the application data collection file 6, that is, the recorded subfiles are deleted by the collection file maintenance processing unit 13 for each subfile according to an instruction from the input unit 10. The collection file maintenance processing unit 13 may delete the subfile in the application data collection file 6 when the application 14 is started.

On the other hand, as a result of the above judgment, if the data IDs do not match, the data is transferred to the error file 8.

In response to a display instruction from the input unit 10, the fetched data error list output processing unit 9 displays the error data on the display screen of the CRT 11. Further, in response to a print instruction from the input unit 10, the fetched data error list output processing unit 9 outputs the error data as an error list 12 using a form or the like. Further, the fetched data error list output processing unit 9 erases the contents of the error file 8 according to a erasing instruction from the input unit 10. Since it is possible that the error file 8 accumulates too much data, the data may be automatically erased in order from the first one at a predetermined time or when data is accumulated to some extent.

A magnetic tape device (MT) 2
And data of floppy disk device (FD) 3 etc.
According to an option instruction from the input unit 10, the code is converted into a uniform format and recorded in the application data collection file 6. Here, the simulation process will be described.

The simulation process is to start a business application program and simulate the business.

In this case, in accordance with the simulation instruction, the simulation processing unit 15 reads data of a certain sequence (data for testing) from the simulation file 4. Then, this data is recorded in the application data collection file 6 as a simulation sub-file.

Therefore, when a new application program is created, by reading the sub file from the application data collection file 6, the operation of the program can be confirmed without inputting actual business data.

As described above, according to the data collecting apparatus of this embodiment, another CPU, magnetic tape device (MT)
2. Since data from information resources such as the floppy disk device (FD) 3 are unified in the data format and recorded in the application data collection file 6, the application program for using these data is It is enough to make something for accessing the file 6 without paying attention to the code system of
Improves software creation efficiency.

Further, since the data window is unified only in the application data collection file 6, it becomes easy for the data users to use it.

Data from the other CPU, magnetic tape device (MT) 2, floppy disk device (FD) 3, etc. is retained until the application program operates, so that the consistency with other systems is maintained as before. Can be kept.

Data unnecessary for the system is rejected to the error file 8 as data other than the defined data, so that they can be confirmed on the display screen of the CRT 11 or the error list 12.

Further, by storing code conversion data for various jobs in the option instruction file 5, it is possible to deal with various codes.

Further, the simulation processing unit 15 reads the test data from the simulation file 4 and records it in the application data collection file 6 as a simulation sub-file. By reading the sub file from the application data collection file 6 when it is created, the operation of the program can be confirmed without inputting actual business data.

Furthermore, the application data collection file 6 can be positioned in the middle of the basic software (OS) and the application program, and the distinction between the two can be clarified.

Data from the other CPU, magnetic tape device (MT) 2 and floppy disk device (FD) 3 are data collection file 6 for application.
Since it is stored in the error file 8 or the error file 8, the timing of erasing data can be controlled. For example, important data can be erased after checking even after executing the application program. It is also possible to automatically delete the data linked with the application program.

[0041]
