Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a version management system, and more particularly to a version management system for managing a file and a combination of files in a computer system.

[Conventional technology]

The traditional version control method for file version control is:
As shown in FIG. 6, a file management means for managing a file (a file system generally called a file system in a computer system, stores data that can be handled by the computer system in a unit called a file, and It is a means of managing based on a structure, in which a hierarchical structure is often used, and a file can be uniquely identified in such a structure. In this case, this is done by giving a unique identifier to the file. Hereinafter, this identifier is referred to as a file identifier) 61, a file content management means 62 for managing the contents of the file, and a version identifier (identifying the version of the file). File version information management means 63 for managing the association between the file information and the contents of the file. A file version registration unit 64 for performing version registration of the specified file (giving a version identifier to the content of the current file (the latest version file) and registering the content so that it can be reproduced later); File version reproducing means 65 for performing version reproduction of a file whose file identifier and version identifier are specified by an operator (reproducing the contents of the version specified by the version identifier for the file specified by the file identifier); It is comprised including.

In such a conventional version management method, the following processing is performed.

The file version registration means 64, when instructed by a version registration operator of a specific file or the like, instructs the file content management means 62 to register the content of the specified file.

The file content management means 62 stores (registers) the content of the specified file so that it can be reproduced later,
Information necessary for extracting the contents of the file is returned to the file version registration means 64.

As a method of storing the contents of a file, there are a method of copying the contents of the file to another file, a method of storing only the difference from the contents of the file registered up to that time, and the like.

The file version registration means 64 stores a combination of three pieces of information of a file identifier of a specified file, a version identifier for identifying the version of the file, and information necessary for extracting the contents of the file. Store in 63.

Further, when the file identifier and the version identifier are specified by an operator or the like, the file version reproducing means 65 refers to the file version information management means 63 to specify the file identifier specified by the file identifier and the version identifier. Is reproduced from the file content management means 62.

[Problems to be solved by the invention]

In general, since work on a computer system is performed using multiple files, it is not only possible to simply manage the version of each file, but also to determine how and which versions of which files were combined. If version management cannot be performed on the indicated combination information (file combination information), the version management is insufficient.

In the above-mentioned conventional version management method, only version management (version registration and version reproduction, etc.) of individual files can be performed (there is only a version management function for a single file). Has a drawback in that it requires a lot of instructions by the operator and recording of how to combine files, etc. (work for version management of file combination information is complicated, and errors tend to occur in the course of the work). .

In view of the above, it is an object of the present invention to easily perform both version management of individual files and version management of file combination information for a plurality of files when work is performed. It is to provide a version control method that can be used.

I have.

Next, the operation of the thus configured version control system of the present embodiment will be described.

The worker describes file combination information (file combination information in which the version identifier in FIG. 4 is not yet described) indicating a list (combination) of files required for the work when performing a certain work (file The management means 16 manages a file in which the file combination information is stored).

When such version registration of the file combination information (version registration of the file and the file combination information identified by the file identifier and the file combination information identifier listed in the file combination information) is instructed by an operator or the like, The version registration means 11 performs the following processing (version registration processing) based on this instruction (see FIG. 2).

First, when the file combination information identifier to be subjected to version registration is given by the above-mentioned instruction, the file combination information management means 14 is fetched so as to take out the designated file combination information (identified by the file combination information identifier). Instructs (the file combination information management means 14 transmits the file combination information designated based on the instruction (the file storing the file combination information) to the file management means.
16) (Step 21).

Next, among the members of the file combination information extracted in step 21, unprocessed members (the members identified by the file identifier or the file combination information identifier or the members whose version registration of the file combination information has not been completed)
Is determined (step 22).

If there is an unprocessed member in this determination, one member is selected from the unprocessed members (step 2).
3).

Next, it is determined whether the member selected in step 23 is related to a file identifier (step 24).

If the member is related to the file identifier in this determination, the file identifier is passed to the file version management means 13 to instruct the version registration of the file associated with the file identifier (the file version management means 13 The version of the file managed by the file management means 16 is registered based on the instruction, and the version identifier given by the version registration is returned to the version registration means 11) (step 25).

If it is determined in step 24 that the member is not related to the file identifier (if the member is related to the file combination information identifier), the file combination information identifier is recursively passed to the version registration unit 11 and the file Instructs version registration of combination information (version registration means
11 performs the version registration process shown in FIG. 2 for the file combination information based on this instruction, and recursively returns the version identifier given in this version registration to the version registration means 11 (step 26).

When the processing in step 25 or 26 is completed, the version identifier returned from the file version management means 13 or the version registration means 11 is described in the member selected in step 23 via the file combination information management means 14 (step 27). ), Step
Control is returned to the judgment of 22.

If there is no unprocessed member in the determination in step 22 (if the processing and determination in steps 23 to 27 have been completed for all members in the file combination information extracted in step 21), the file combination Instruct the file version management means 13 to register the version of the file storing the information (the file version management means 13 registers the version of the file, and stores the version identifier given by this version registration in the version registration means 11

The file combination information identifier and the version identifier are specified, and the version of the file combination information is reproduced (the version of the file identified by the file identifier and the file combination information identifier enumerated in the file combination information and the file combination information are reproduced). When instructed by an operator or the like, the plate reproduction means 12 performs the following processing (plate reproduction processing) based on the instruction (see FIG. 3).

First, when the file combination information identifier and the version identifier to be reproduced are given by the above instruction, the file combination information management means 14 is made to reproduce the contents of the specified version of the specified file combination information. (The file combination information management means 14 knows the version identifier of the file storing the file combination information based on the version identifier correspondence information in the version identifier correspondence information management means 15 and uses the file version management means 13 A plate reproduction for extracting the file combination information is performed (step 31).

Next, among the members included in the list in the file combination information extracted in step 31, unprocessed members (file reproduction of the file or file combination information identified by the file identifier or the file combination information identifier has been completed). Is determined (step 32).

If there is an unprocessed member in this determination, one member is selected from the unprocessed members (step 3).
3).

Next, it is determined whether the member selected in step 33 is related to a file identifier (step 3).
Four).

If the member is related to the file identifier in this determination, the file identifier and the version identifier stored in the member associated with the file identifier are passed to the file Instructs to reproduce the version (the file version management means 13 reproduces the contents of the file specified by the file identifier and the version identifier based on the instruction) (step 3).
Five).

If it is determined in step 34 that the member is not related to the file identifier (if the member is related to the file combination information identifier), the member is associated with the file combination information identifier and the file combination information identifier. The version identifier stored therein is recursively passed to the version reproducing means 12 to give an instruction to reproduce the version of the file combination information (the version reproducing means 12 sends the file combination information identifier and the version The plate reproduction process shown in FIG. 3 for the file combination information specified by the identifier is performed (step 36).

When the processing of step 35 or 36 ends, step 32
The control is returned to the determination of.

If there is no unprocessed member in the judgment in step 32 (if the processing and judgment in steps 33 to 36 have been completed for all members in the file combination information reproduced in step 31), the plate is reproduced. The process ends.
