Abstract

PURPOSE: To manage the program correction history by performing the addition or correction of a function to an extracted program and registering difference in that corrected program onto a function history file and a common history file. CONSTITUTION: The correction record 31 of a function history file 16 and the correction record 33 of a common history file 17 are generated by a registering means 3. Next, a program file 12 for conditions B is extracted out of the function history file 16 and the common history file 17 by an extracting means 1. Further, a correction record 34 is registered on the common history file 17 and a correction record 32 is registered on the function history file 16 by the registering means 3. Then, a program for conditions A is extracted from the function history file 16 and the common history file 17 to a program file 14 by the extracting means 1. At such a time, the program file 14 contains function difference 21 and common part correction 23.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program (computer program) difference management system, and more particularly to a function common to all programs and a function unique to each program executed when a specific condition is satisfied. The present invention relates to a program difference management method that manages a plurality of programs having a difference (a part that realizes a function unique to each program (including a function common to a plurality of programs, not all)).

[0002]

2. Description of the Related Art Conventionally, this type of technology has been aware of centrally managing a plurality of programs having partially different functions. However, regarding the management of revision histories of the plurality of programs at the same time, I wasn't aware. In other words, it was not possible to restore the corrected parts.

A conventional program difference management system is disclosed in Japanese Patent Laid-Open No. 2-159931.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a program difference management system capable of managing a program modification history in addition to the conventional technique.

[0005]

According to the program difference management method of the present invention, a fetching means for fetching a specific program from a function history file and a common history file based on a fetching condition relating to the specific program, and the fetching means. And a registering unit for registering a difference in the modified program modified by the modifying unit to the function history file and the common history file. Characterize.

[0006]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the program difference management system of the present invention. The program difference management system according to the present embodiment has a fetching unit 1, a correcting unit 2, a registering unit 3, and program files 11 and 1.
2, 13, 14, a function history file 16 and a common history file 17 are included.

The program file 11 has a function difference 21.
It is configured to include.

The program file 13 has a function difference 22.
And a common part correction 23.

The program file 14 has a function difference 21.
And a common part correction 23.

The function difference 21 has a fetch condition 41 for instructing to fetch the difference relating to the function difference 21 when the condition A is satisfied, and the function difference 22 is a function difference when the condition B is satisfied. It has a retrieval condition 42 for instructing to retrieve the difference concerning 22. (Figure 1
Medium “IF condition = A” and “END” and “IF
“Condition = B” and “END” are simplification of the extraction conditions 41 and 42. Next, the operation of the program history management system of this embodiment having the above-described configuration will be described. In addition, here, the function difference 22 related to the condition B is added to the program file 11 including the common part and the function difference 21 related to the condition A (when adding a unique function when the condition B is satisfied).
Then, immediately after that, the operation of referring to the latest program relating to the condition A will be described.

First, the registration means 3 generates a correction record 31 of the function history file 16 and a correction record 33 of the common history file 17.

Next, the extracting means 1 extracts the program file 12 for the condition B (the program executed when the condition B is satisfied) from the function history file 16 and the common history file 17. In this case, since the history related to condition B does not exist, a program including only the common part is obtained as the program file 12. Next, by the correction means 2, the program file 1
2, the program file 13 in which the function difference 22 related to the condition B and the common part correction 23 are added is generated.

Further, the registration means 3 registers the correction record 34 in the common history file 17 and the correction record 32 in the function history file 16. (Addition and correction of functions common to conditions A and B will be completed by a single process.) Next, the extraction unit 1 extracts the program of condition A from the function history file 16 and the common history file 17. Are fetched into the program file 14. At this time, the program file 14 includes the function difference 21 and the common part correction 23.

In the above description, the modification of the common part is described, but the modification of the functional part can be performed in the same procedure.

In the above description, reference has been made to the latest program relating to condition A, but reference to an old program (a program before changing the common part) can also be performed in the same procedure.

[0017]

As described above, according to the present invention, by changing the processes of the extracting means and the registering means, it is possible to centrally manage a plurality of programs having unique functions, and also to modify the history of the plurality of programs. It has the effect of being manageable.
