Abstract

PURPOSE:To update the text data on all versions in a batch just with update of the text data on a source version by updating the differential information on each version via a differential information updating means in accordance with the updating result of the source version. CONSTITUTION:A text data updating means 2 updates the text data on a source version stored in a base file 3 in response to an instruction given from an input means 1. The difference information obtained between the updated text data on the source version and the unupdated text data is stored in a base file differential information file 6. Then a differential information updating means 8 updates a differential information file 7 which stores the differential information on each immediately preceding version following the unupdated source version. Thus it is possible to eliminate the discordance among the differential information on other versions that may possibly be caused with update of the source version and to update plural versions in a batch.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention manages multiple versions of text data using original version text data and difference information for each subsequent version with respect to the immediately previous version. This paper relates to a method for updating multiple versions at once in a text data management mechanism.

[Conventional technology]

As a mechanism for collectively managing multiple versions of text data, the original version of the text data is managed by storing it in its entirety, and subsequent versions of the text data are managed by storing the difference information between the text data of the previous version and the above original version. A text data management mechanism is known that manages text data based on versions.

According to such a mechanism, there is no need to store the entire text data of each version, so there is an advantage that the file capacity can be extremely reduced.

In this mechanism, a certain version of text data is restored by sequentially reflecting the difference information of each version up to that version on the original version of text data. Therefore, it is not allowed to update or delete only a specific version of text data prior to the latest version. That is, in the conventional text data management mechanism, only the latest version of text data is subject to update. For this reason, in order to update all versions at once, conventionally a method of following steps 41, 42, and 43 shown in FIG. 4 has been adopted.

■Step 41 By repeating the process of generating restored text data i using the immediately previous version of the text data (restored text data me 1; where i is 1 to n) and the difference information l, all versions of the text Restore data.

■Step 42 The text data of the original version (base text data) and the text data of each restored version (
The file update means individually updates each of the restored text data (restored text data) and registers the results.

■Step 43 The updated text data of each version obtained in step 42 is registered in the conventional text data management mechanism in verge order. Through this registration, the text data management mechanism manages multiple versions of text data using the entire updated base text data and updated difference information indicating the difference between each version.

[Problem to be solved by the invention]

In the conventional text data management mechanism that manages multiple versions of text data using the original version of text data and the difference information between each version, the conventional text data management mechanism performs the same update for all versions by performing steps 41 to 43 described above. In this method, the text data for each version is restored using the difference information, updated for each version, and then registered in the order of versions, which requires a lot of time and file capacity to restore all versions. Become. In addition, the same update is performed individually for each managed version, which is time-consuming.

The present invention has been made in view of these circumstances,
The purpose is to provide a multiple vergebond batch update method that eliminates the need for individual updates and registrations for restoring all versions of text data, thus saving file capacity and processing time.

[Means to solve the problem]

In order to achieve the above object, the multiple verge run batch update method of the present invention uses a base file that stores the text data of the original version, and difference information that stores the difference information for each version after the original version with respect to the immediately previous version. In a text data management mechanism that manages a plurality of versions of text data using a file, a text data updating means updates the original version of text data stored in the base file in response to an instruction from a human power means; a base file difference information file that stores difference information between the original version text data before updating and the original version text data updated by the text data update means; , a difference information update means for updating the difference information in the difference information file, and outputting predetermined information by an output means if the updated part of the current original version has already been updated in a certain version. ing.

[Effect]

In the multiple version batch update method of the present invention, the text data update means updates the original version text data stored in the base file in response to an instruction from the input means, and combines the updated original version text data with the text data of the updated original version. A base file difference information file stores difference information from the text data before update, and based on the contents of this base file difference information file, the difference information update means updates the immediately preceding virgin data for each version after the original version before update. By updating the difference information file that stores the difference information of If the version has already been updated, the necessary information is provided to the user by outputting predetermined information from the output means.

[Example] Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of the main parts of a text data management mechanism to which the multiple barge town batch update method of the present invention is applied. In the figure, a base file 3 and a difference information file 7 are files that have traditionally existed to manage multiple versions of text data, and the base file 3 stores the text data of the original version, and the difference information file 7 Difference information for each version other than the original version with respect to the immediately previous version is stored in .

The primitive virgin tongue is read out from the base file 3 and provided to the user, and each virgin tongue other than the primitive virgin tongue has each difference information of the corresponding version salt stored in the difference information file 7 sequentially added to the original version of the base file 3. Although the data is restored with added features and provided to the user, the means for realizing this is the same as in the past, so illustration is omitted. Other components, namely input means 1. File update means 2゜Updated base file 4. Difference information generation means 5゜base file difference information file 6, difference information update means 8
and output means 9 are functional units related to the multiple barge run batch update method of this embodiment, and each has the following functions.

- Input means 1 A function that accepts update instructions for the original version from the user and transmits them to the file update means 2.

-File update means 2 A function of updating the original version of text data stored in the base file 3 according to the update instruction transmitted from the human power means 1, and writing the updated text data to the updated base file 4.

-Updated base file 4 A function to hold the text data of the updated original version 5.The contents of the base file 3 will be saved in this updated base file 4 after the batch update process for multiple versions is completed.
The content can be replaced by 1.

Difference information generation means 5 Difference information between the text data stored in the updated base file 4 and the text data stored in the base file 3, that is, difference information between the original version text data after the update process and the original text data A function that generates a line number correspondence table that matches the line numbers of the original version of text data before and after the update.

-Base file difference information file 6 A function to hold the difference information generated by the difference information generation means 5 and necessary tables.

- Difference information update means 8 Based on the contents of the base file difference information file 6, updates the difference information of each verge run stored in the difference information file 7, and also updates the updated part of the current primitive vergetan that has already been updated in a certain vergetan. A function to transmit predetermined information to an output means when

- Output means 9 A function to perform CRT display, printout, etc. in order to notify the user of the information transmitted from the difference information update means 8.

FIG. 2 is a flowchart showing the process flow of the second method of updating a plurality of virgins at once according to this embodiment, and the operation shown in FIG. 1 will be explained below along with the flow shown in FIG.

When the user inputs an instruction to update the original version from the input means 1, the file update means 2 updates the text data of the original version in the base file 3 according to the instruction, and converts the contents of the updated base file 3 into the updated base. Store in file 4 (process 21) 0 Next, the difference information generation means 5 operates to generate difference information from the base file 3 and the updated base file 4, as well as generate a line number correspondence table, and transfer this to the base file. It is stored in the difference information file 6 (processing 22).

Next, the difference information updating means 8 operates and performs processes 23 to 25. First, the difference information of the youngest version in the difference information file 7 is set as the current version (process 23
). Next, extract the difference information one by one from the current version, update it if necessary according to the contents of the base file difference information file 6, and repeat the operation of generating predetermined information to update the difference information of the current version. (Process 24) Then, it is determined whether or not there is an unprocessed version left in the difference information file 7. Process 25). If there is, the process returns to Process 23 and sets the current version to the next version, as described above. After repeating the operation and completing processing for all versions, control is passed to the file updating means 2. When control is passed, the file update means 2 stores the contents of the updated base file 4 in the base file 3 (processing 26).

This completes the series of multiple-version batch update processing operations.

Next, the operation of the difference information updating means 8 will be explained in more detail with reference to FIG. 3 showing an example of internal processing of the difference information updating process 24 shown in FIG.

The difference information update means 8 inputs a code from the difference information of the current version (31), and determines whether or not the currently input record needs to be updated based on the contents of that record and the contents of the base file difference information file 6. Judgmentally process 32), update it if necessary (process 33)
). For example, if the text line "A" in the original source version has already been updated to the text line "A゛" in the immediately subsequent version, a record of the difference information exists, but the update in the source version For example, if the text line "r A" above is updated to "A"J during processing, if you leave the record of the difference information as is, the text line "A" will be updated in all versions at once. Therefore, in such a case, the difference information is updated. Additionally, a problem may occur if a text line that has already been deleted in a certain version is deleted in the current update of the original version, so the difference information is updated accordingly. And in these cases,
Since it is desirable to notify the user to that effect, in the next process 34, if the update has already been made, the output means 9 outputs, for example, the version identifier line 9 number, the updated image for that version, etc. In the case of deletion, a process such as 0 or more is performed for all records of the difference information of the current version to output that fact, the version identifier 1 line number, etc. from the output means 9 (process 35).

〔Effect of the invention〕

As explained above, in the multiple version batch update method of the present invention, while it is possible to update the original version of the base file, which was previously not allowed to be updated, by the text data update means, it is not possible to update the original version of the base file by using the text data updating means. Since the desired text data cannot be obtained when restoring another version due to inconsistency, the difference information of each version is updated by a difference information update means according to the update result of the original version. All versions of text data can be updated at once by simply updating the original version of text data. Therefore, the effort of restoring, updating, and registering all versions of text data, which was conventionally necessary, is eliminated, and at the same time, file capacity and processing time are saved. In addition, if the updated part of the current source version has already been updated in a certain version, predetermined information indicating the situation will be output from the output means, so the user can check the impact of the batch update process on multiple versions. etc. can be easily known.
