DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data check apparatus for checking and displaying data when debugging software.

[0002]

2. Description of the Related Art Hitherto, it has been an important factor in software development how to finish software development in a short time and to maintain high quality of the software.

Generally, in the course of software development, the entire software is not operated from the beginning, but the software is partially tested, and the entire test is performed when the test is completed. When testing a part of the software, the test software for testing the software is written directly to the software, and as a result, it is determined whether or not the expected data is output. In many cases, it is necessary to determine whether there is an underlying bug. For example,
In the case of a program for changing an external data file, as shown in the flowchart of FIG. 4, the type (type) of a variable used in the program is set or an initial value is substituted (S11), and various application programs are changed. (S12, S13), execute a debugging program for checking how the data added to the application program changes, read data from the data file (S14), and set the read data as a set value. It is compared and checked whether it is appropriate (S15). If the read data is not the set value, the data is changed (S16), the data is read again from the data file (S17), and a check is made by comparing the changed data with the read data (S18).
Execute another application program (S1
9).

As described above, a test program for the data reading process and a test program for the data check process are tested to determine how the data in the write data file is rewritten in the program under development to determine whether there is a bug. Then, after determining that there is no bug, the test program is deleted or changed from the program under development, and the other parts are further tested in the same manner.

[0005]

However, deleting or changing the test software after the completion of the debugging of the software under development is likely to reduce the quality of the software due to the deletion of necessary parts of the software under development or Since the source program has to be changed, the work time has been increased or the work time has been increased by setting check items in detail.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data check device capable of checking data without inserting test software for software debugging.

[0007]

According to the present invention for achieving the above object, a program under development is executed to execute the program.
By comparing the processing result data, the program
A data check device for debugging the system,
A first data storage means for storing the data after this processing by executing the programs, and the second data storage means for storing the data after the last treatment, stored in said second storage means and the first storage means a data reading means for reading are data for each predetermined period, the definition information broom憶means format data for displaying the data is stored, said the current read every constant period by said data reading means Data comparing means for comparing data with the previous data to check for updated data; and editing data updated and checked by the data comparing means in accordance with the format of data stored in the definition information storage means. It has data editing means and data display means for displaying data edited by the data editing means. It is a data check device to.

[0008]

The data check device of the present invention executes a program, stores data after the current processing in the first data storage means in the first data storage means, and stores the data after the previous processing in the second data storage means. The data is read by the data reading means at each cycle. The read data is compared by the data comparing means and the updated data is checked. Further, the data editing means edits the data in accordance with the data format of the definition information data storage means in which the data format for displaying the updated data is stored. Then, the edited data is displayed by the data display means.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A data check device according to the present invention will be described below with reference to the accompanying drawings.

The data check device of the present invention includes a data comparison member 1 for writing and reading data and comparing data when the software under development is operated as shown in FIG. There is a data display member 2 that edits and displays data from the.

The data comparison member 1 has a first data file 15 as first data storage means for storing data processed this time by executing software under development, and a second data file for storing data processed last time. A second data file 17 serving as a storage unit, a data reading unit 11 serving as a data reading unit that reads data processed at this time from the first data file at regular intervals, and a data reading unit configured to read previously processed data from the second data file 17. There is a data comparison unit 13 that is a data comparison unit that reads and compares the read data with the currently processed data.

The data display member 2 has a data editing unit 21 serving as a data editing unit for editing data in order to display updated data compared and checked by the data comparing unit 13. Information data file 23 which is a definition information storage means storing information such as a format for the
There is a data display unit 25 which is a data display means for displaying data from the server.

[0013] Such a data check device operates as follows.

For example, when a program for writing data to the first data file 15 is to be debugged, the program is first operated using previously known data and written into the first file. The data reading unit 11 reads the data written this time in the first data file at regular intervals, compares the data written this time with the data written last time by the data comparing unit, and determines that the data has been updated this time. The data is transmitted to the data editing unit 21 and the data written this time is written to the second file 17. Then, the data editing unit 21 reads a format for data display from the definition information data file 23 and edits the data changed this time for display. The edited data is displayed on the data display section 25 as shown in FIG. 2, the engine number, the production date, the point passing mark which is a check point of the product quality, and the number of defects in the production process.

FIG. 3 is a flowchart of control of the data check device of the present invention.

The data processed this time is read from the first data file by the data reading means 11 (S
1). Further, the previously processed data is read from the second data file by the data comparing means (S2), and the currently processed data and the previously processed data are compared one by one (S3). Record numbers are allocated and stored in the order in which the comparison result data is updated (S5).
If the data has not been updated (S4), it is checked whether it is the last file (S6), and if it is not the last file, the data is compared again one by one. The current data used for this comparison is written to the second data file (S7). Then, after the updated data is read by the data editing unit 21 into the definition information data file 23 (S8), the definition information data file 2
3 are edited in the order of the stored record numbers (S9). The edited data is displayed on the data display device 25.
Will be displayed.

By configuring and operating in this way,
The data check device of the present invention inserts or deletes software for debugging into software under development by comparing previously processed data and data processed this time when running software under development Without having to do this, you can check and display data that is processed by the software under development.

[0018]

As described above, according to the data check device of the present invention, the software for debugging is processed by the software under development without inserting or deleting the software for development under software. Since the data can be checked and displayed, the quality of software under development due to erroneous insertion or erroneous deletion of debugging software can be prevented.
