Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file registration / retrieval device for retrieving a file that meets a retrieval condition.

[0002]

2. Description of the Related Art As an example of a conventional data management system, for example, "JStar Workstation" (P144 to P15) issued by Maruzen Co., Ltd. on April 25, 1986.
There is one disclosed in 7). In the document document registration search function of the workstation disclosed in this document,
A special symbol ““ ”(hereinafter referred to as“ special frame ”) called a field is inserted into a variable item of a fixed form document to handle it separately from the text, and a dedicated command is provided for entering a character string into this special frame. By doing so, it is possible to easily create a standard document.Character strings in a plurality of special frames in one document (hereinafter referred to as special frame values)
By using a record file that manages the data in which the combination of 1 and 2 is used as one record, a record satisfying the condition specified by the user can be searched from a large number of records.

[0003]

However, in the above-mentioned conventional data management by the record file, since only the value of the special frame of the record satisfying the condition specified by the user is displayed as a result, a document such as a document header is displayed. It was unsuitable for handling documents that differed from the main one, because only a part of was common. That is, the record file could not store or retrieve the document file. Of course,
It was also not possible to store and retrieve files (for example, image data) whose contents were not character strings.

An object of the present invention is to search for a desired file from a plurality of files having a common part in the content items, and to provide a file having a character string and a content other than the character string. It is to provide a file registration / retrieval device capable of retrieving the following files.

[0005]

To achieve the above object, the present invention provides a search file in which a name of a special frame and a character string in the special frame are registered, and a predetermined file corresponding to the search file. First storage means for storing the files and directories for managing these files, extraction means for extracting the name and character string in the search file, and the name extracted by the extraction means. Corresponding to the character string and the storage destination information of the directory in the first storage means are stored in association with each other; The second storage means is searched, and the searching means for searching the target file from the first storage means based on the search result.

[0006]

In the file registration / retrieval apparatus according to the present invention, when the retrieval target file is stored, the first storage means manages the retrieval file, a predetermined file corresponding to the retrieval file, and these files. A directory is stored, and a character string in the special frame corresponding to the name of the special frame extracted from the search file by the extraction unit is associated with the storage destination information of the directory in the second storage unit. Are stored. At the time of searching for a file, the searching means extracts a character string that matches the character string specified as the search condition from the second storage means, and stores the stored character string corresponding to the extracted character string. Based on the destination information, the corresponding directory is retrieved from the first storage unit together with the search file managed by the directory and a predetermined file, and a file that meets the search condition is searched.

Therefore, according to the present invention, the file to be searched is stored and managed under the directory together with the search file, and the content is not a character string (for example, a file storing image data). You can even search for that file.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a network system including a file registration / retrieval device according to the present invention.

In FIG. 1, a file registration / retrieval device 10
Is a workstation 30 via the network 20.
The search target file stored in itself is searched according to the search instruction input from the workstation 30, and the search result is returned to the workstation 30. The search result is workstation 3
0 is displayed on a display device (not shown) provided in
It is printed by a printer (not shown). The workstation 30 generates a file management unit 31 that transfers, moves, or deletes files, a file storage unit 32 that stores data, a directory, a search file, a file to be searched such as a document file or an image data file. In addition, the file editing unit 33 for editing the file and the network 2 connected to the network 20
It is composed of a data communication unit 34 that inputs and outputs data via 0.

The file registration / retrieval device 10 comprises a retrieval attribute extraction unit 11, a retrieval attribute storage table creation unit 12, a retrieval attribute storage table storage unit 13, a file storage unit 14, an attribute retrieval unit 15, and a data communication unit 16. Has been done.

The search attribute extraction unit 11 recognizes the name and order of the special frame and the character string in the special frame which are inserted into the character string of the search file and in which the character string can be written. That is, the data extracted from the names and order of the special frames 210, 220, 230 in the search file 200 as shown in FIG. 2 input through the data communication unit 16 and the names and order of the special frames are unique. Extract the distinguishable attribute data. The special frame is indicated by "" in Fig. 2. The characters "image data name", "creator", and "creation date" written to the left of each special frame in Fig. 2 are for searching. When registering a file, it is entered using the character input function of the system so that the operator can know what the attributes of the special frame are.

By the way, the search attribute extraction unit 11 sends the extracted data to the search attribute storage table creation unit 12 when the search file is registered, and the search attribute storage table storage unit based on the attribute data when the predetermined file is stored. 1
A search attribute storage table matching the extracted data or the attribute data is selected from the search attribute storage tables stored in No. 3, and a pointer for extracting the input file is added to the corresponding table. This pointer is information indicating where in the file storage unit 14 a directory for managing a file to be searched such as a document file or an image data file is stored.

From the search file 200, the special frame 21
In the example shown in FIG. 2, “image data name”, “creator”, and “creation date” are extracted as the names 0, 220, and 230, that is, the attributes of each special frame. As for the order of the special frames, for example, the order of the special frame "image data name" is set to 1, and the order of "special frame 1" is given to this special frame. “Special frame 2” is assigned with the second rank, and “special frame 3” is assigned with the third rank for the special frame “creation date”.
The order of the special frames is determined by the extraction order when extracting the names of the special frames. Therefore, in the example shown in FIG. 2, the special frame “image data name” is first extracted, and then the special frame “creator” and the special frame “creation date” are sequentially extracted.

The search attribute storage table creating unit 12 creates a search attribute storage table having columns corresponding to the names of the special frames according to the names and order of the special frames extracted by the search attribute extracting unit 11. An example of this search attribute storage table is shown in FIG. In the example shown in this figure, the search attribute storage table 300 has three columns in which the character strings in the special frame corresponding to the names of the special frames in the search file shown in FIG. File and a column in which storage location information of a directory for managing a predetermined file to be searched is registered. In the example shown in FIG. 2, a table having columns 310, 320 and 330 corresponding to the names of the special frames and a column 340 of pointers as storage destination information is created. Such a table is created for each search file and stored in the search attribute storage table storage unit 13.

When the search attribute storage table thus created is stored in the search attribute storage table storage unit 13, a name is given to the table and a file having the same name is provided as an attribute. For example, the name of the table 300 shown in FIG. 3 is changed to “Table: image data name / creator /
Created date "," Table: image data name / creator /
The attribute data "creation date" is used as the attribute of the search file. By using the attribute data that can uniquely distinguish the name and order of the special frame, the name and order of the special frame in the search file are extracted. Save time to do

The search attribute storage table storage section 13 stores the table created by the search attribute storage table creation section 12 in addition to the existing table.

The file storage unit 5 stores a search file 200 input through the data communication unit 16 when storing search target files, search target files corresponding to the search files, and directories for managing these files. To do.

The attribute search unit 15 selects a corresponding search attribute storage table stored in the search attribute storage table storage unit 13 based on the input search condition, and uses the pointer of this table to select the file storage unit. 14 is searched, and the result is output to the data communication unit 16.

In this embodiment, the search attribute extraction unit 11
According to the name of the special frame extracted by, the search attribute storage table creating unit 12 creates the table as shown in FIG. 3, but without creating the table,
The name of the extracted special frame, the character string input in the special frame corresponding to this name, and the storage destination information of the directory may be stored in association with each other. But,
By creating a search attribute storage table as preprocessing and registering the above information in this table, the search processing at the time of file search can be performed quickly. Therefore, create the table as in this embodiment. Is preferred.

Further, in this embodiment, the above-mentioned extracting means is constituted by the search attribute extracting section 11, the above-mentioned first storing means is constituted by the file storing means, and the above-mentioned second storing means is constituted. Search attribute storage table storage unit 13
The search means described above is the attribute search unit 15
It is composed of.

The general operation of the file registration / retrieval apparatus having the above-mentioned structure will be described. When the search target file is stored, the search attribute extraction unit 11 stores the search file together with the search target file in the entire directory that constructs a hierarchical structure of files (this directory is a directory for managing the search file and the search target file). Different from each other) is stored in the file storage unit 14 for each directory for managing the search file and the search target file (this directory is an element that constitutes the above-mentioned entire directory). Hereinafter, in this embodiment, in order to distinguish the whole directory from the directories as the elements constituting the directory, the directories as the elements are simply referred to as “directories” and the whole directories are referred to as the “entire directories”. To

Further, the search attribute extraction unit 11 extracts a set of names of special frames and a character string in the special frame inserted in the search file as many as the number of search files to obtain a character string in the special frame. A pointer to the directory in the file storage unit 4 is inserted into the search attribute storage table corresponding to the search file.

At the time of searching for the file to be searched, the attribute search unit 15 stores the search attribute storage table stored in the search attribute storage table storage unit 13 according to the condition for the character string in the special frame specified by the user. By searching for, the search target file stored together with the search file satisfying the condition for the character string in the special frame specified by the user is searched.

Next, the process of registering the search file will be described with reference to the flowchart shown in FIG.

The search file is the workstation 30.
From the file registration search device 1 through the data communication unit 16
When 0 is input (step 401), the search attribute extraction unit 11 extracts the name of the special frame in the search file (step 402), and this is used as the search attribute storage table creation unit 1
Pass to 2. The search attribute storage table creation unit 12 creates a table having columns corresponding to the names of the special frames as a search attribute storage table (step 403) and additionally registers it in the search attribute storage table storage unit 13.

Next, the file storage processing will be described with reference to the flowchart shown in FIG.

When the file for search, the file to be searched, and the directory are input to the file registration / search device 10 through the data communication unit 16, the search attribute extraction unit 11 operates as shown in FIG.
As shown in (1), it is determined whether or not it is a directory (step 501), and in the case of a directory, N = 1 is defined (step 502), and then it is determined whether or not the Nth file is a search file ( Step 503). If the Nth file is a search file, the name of the special frame in the search file is extracted (step 504), and the search attribute storage table in which the name of the special frame matches is retrieved attribute storage table storage unit 13 Is selected (step 505) and the set of character strings in the special frame is additionally registered as a row (row) in the selected table (step 506).

After that, it is checked whether a file managed under the above directory still exists (step 507), and if the file still exists, "N = N +".
1 ”is calculated (step 508), and then the above step 5
Returning to step 03, the steps after this step are executed. On the other hand, if there are no more files, the search file is stored in the file storage unit 14 for each directory under the entire directory together with the search target file (step 509).
Then, the pointer (address information) to the directory is registered in the corresponding row of the search attribute storage table in step 506 (step 510). If “NO” in steps 501 and 503, the corresponding file is stored in the file storage unit 14 (step 5
11).

Next, the storage process will be described with a specific example.

Now, let us consider a case where the search target file A in which the image data showing the outline drawing 1 is stored is stored. In the workstation 30 as a client, for the search file 200 shown in FIG. 2, "Outline drawing 1" as the image data name in the special frame 210 and "A" as the creator's name in the special frame 220 are special Frame 23
It is assumed that “0, January 1, 1992” is described as the creation date in 0. A file in which such contents are described is referred to as a search file A. Further, as shown in FIG. 6, it is assumed that a directory 600 is created under the folder 1 in which information (node) indicating the search file A and information (node) indicating the search target file A are connected.

The search file A, the search target file A, and the directory 600 are the file registration / search device 1
When input to 0, the file A for search and the file A to be searched are stored in the file storage unit 14, and the directory 600 is stored by being linked to a predetermined area of the entire directory stored in the file storage unit 14. To be done. Further, the contents of the row (row) 710 shown in FIG. 7 are registered in the search attribute storage table 300. That is, in the row 710, the special frames 210, 220, 230 of the search file A are stored in the columns 310, 320, 330, respectively.
The character string in the column is registered, and “Address1” as the storage destination information of the directory 600 is registered in the column 340. Note that the contents of row 720 have not been registered at this point.

Next, when storing the search target file B in which the image data showing the outline drawing 2 is stored, consider the case where it is desired to manage the storage time limit of this file.

Similarly to the above, in the workstation 30, for the search file 200, the special frame 210 has the "outside view 2", the special frame 220 has the "B", and the special frame 23.
It is assumed that 0 describes "1992, X2 month, Y2 day". A file in which such contents are described is referred to as a search file B1. Further, a search file 800 having the content as shown in FIG. 8 is registered to manage the storage deadline, and the storage deadline of this file is “1992, X3, Y3 days” in the special frame 810. , Special frame 820
It is assumed that "C" is described as the administrator's name. The file in which such contents are described is the search file B2.
And Further, as shown in FIG. 9, under the folder 2,
A directory 900 in which information (node) indicating the search file B1, information (node) indicating the search file B2, and information (node) indicating the search target file B are linked.
Is generated.

When the search file 800 is registered, a search attribute storage table corresponding thereto (the actual contents are not registered at this point) is created, and the search attribute storage table is stored. It will be stored in the unit 13.

When the search file B1, the search file B2, the search target file B, and the directory 900 are input to the file registration / search device 10, the search file B1 and the search file B are input in the same manner as the above storage processing.
2. The search target file B is stored in the file storage unit 14, and the directory 900 is stored in the file storage unit 14 linked to a predetermined area of the entire directory.

Further, the contents of row 720 shown in FIG. 7 are registered in the search attribute storage table 300. That is, in row 720, each column 310, 320,
330 includes special frames 210 and 22 of the search file B1.
The character strings in 0 and 230 are registered, and “Address 2” as the storage destination information of the directory 900 is stored in the column 340.
Is registered. Further, when the search file 800 is registered, the search attribute storage table corresponding to the file is created, so that predetermined information is registered in the table. This registered state is shown in FIG. In the example shown in the figure, in the row 1010 of the table 1000, the character strings in the special frames 810 and 820 of the search file B2 are registered in the columns 1020 and 1030, and the storage destination of the directory 900 is stored in the column 1040. “Address 2” as information is registered.

Finally, the file search processing is shown in FIG.
This will be described with reference to the flowchart shown in FIG.

When "image data name = outer view 1 and creator = A" as a search condition is input from the data communication unit 16 to the file registration / search device 10 (step 110).
1) The attribute search unit 15 selects a search attribute storage table corresponding to a given search condition from the search storage table storage unit 13 (step 1102), and a row satisfying the search condition given from the table is selected. Is searched (step 1103). Further, a search is performed using the pointer to the directory in the file storage unit 14, and the result (directory and search target file) is output to the data communication unit 16 (step 1104).

Next, the above-mentioned search processing will be described with a specific example.

First, when "image data name = outer view 1 and creator = A" is given as the search condition 1, the table shown in FIG.
The table 300 shown in is selected, and the contents of the row 710 matching the search condition are extracted. As a result, the file storage unit 14 reads "Address".
1. The directory indicated by 1 (in this example, the directory 600 shown in FIG. 6), this directory 600
The search file A and the search target file A, which are managed under, are read.

Next, when "image data name = outline drawing 2 and creator = B" is given as the search condition 2, the same processing as in the case of the search condition 1 is performed, and as a result, the file is obtained. From the storage unit 14, “Address
The directory indicated by 2 (the directory 900 shown in FIG. 9 in this example), the search file B1, the search file B2, and the search target file B managed under this directory 900 are read.

Further, the retrieval condition 3 is "retention date = 1992.
When X3 · Y3 and administrator = C ”are given, this time, the table 300 shown in FIG. 10 is selected from the tables in the search attribute storage table storage unit 13 and the row matching the search condition is selected. The contents of 1010 are extracted. As a result, since the directory indicated by “Address 2” is referred to, the file storage unit 14
As in the case of the above search condition 3, the directory 900,
The search file B1, the search file B2, and the search target file B are read.

As described above, according to this embodiment, even if the content is not a character string (eg image data), the file can be searched.

Further, for example, by giving either the search condition 2 or the search condition 3 described above, the target search target file B can be searched, and the search condition can be designated from a set of a plurality of items. You can In this embodiment, "image data name, creator,
By designating a desired item from the set of "creation date" or a desired item from the set of "retention period, administrator", the target search target file can be searched.

In this embodiment, the file to be searched is the image data, but it goes without saying that the document file can be searched by using this as a document file.

Therefore, a desired file can be searched from a plurality of files having a common part in the items of contents, for example, any file such as a document file and an image data file.

[0048]

As described above, according to the present invention, the file to be searched is stored and managed under the directory together with the search file, so that the content is not a character string (for example, image data is saved). File), you can search for that file.

Therefore, from the above, it is possible to search for a target file from a plurality of files that have a common part in the items of contents, for example, any file such as a document file and an image data file.
