Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database management program including document data and statistical data, and a data processing system including the data editing processing program.

[0002]

2. Description of the Related Art Conventionally, a data processing system for handling document data, statistical data, etc., which has a plurality of access means, is constructed on the basis of a client / server system, and has a data management function and a data access function. In many cases, a user interface for editing and updating is performed by a program independent of the user interface.

(A) In such a system, it is difficult to use an existing program as a user interface as it is. For example, when an editor program called vi is considered as a user interface, this program can read data from a file or write data to a file, but the data can be written to a program that performs specific data processing or data management. It cannot be passed directly.

Considering an environment composed of a plurality of devices connected by wired / wireless communication means, it has conventionally been necessary to recreate a new program. (B) On the other hand, in the data processing system according to such a system, the data management unit, which is a database server, makes a request generated from a plurality of editing processing programs for single data editing / updating as follows. Processing. In this case, the edit processing program P1 has the data D1.
To edit / update the file, first, edit processing program P1
Receives a request to lock the data D1, stores information indicating that the data D1 is in the locked state, and notifies the edit processing program P1 of acceptance of the lock request. Next, the read request for the data D1 is received from the edit processing program P1, and the data D1 is transmitted. After that, when a request to lock the data D1 is received from another editing processing program P2, the fact that the data D1 is in the locked state is notified. At this time, the other editing processing program P2 abandons editing or waits until the lock is released. In the latter case, the locked state of the data D1 is released as soon as there is a request for writing the data D1 and a request for unlocking or editing cancellation from the editing processing program P1, and then a lock request from another editing processing program P2 can be accepted again. It becomes a state.

According to the data management method by adding the lock information as described above, it is possible to carry out the update processing including the reading of a single data by a plurality of data editing programs which are operating at the same time without losing the consistency. On the other hand, the data edit processing program requires locking / unlocking operations for all data editing, which makes the operability of the user worse than that of a stand-alone data processing system. There was a point.

This means that, for example, one user alternately edits one data under the environment of a multi-window system by using two different data editing programs, for example, a spreadsheet program and a graph drawing program. In this case, each program requires an operation for locking / unlocking alternately, so the operation for that is very troublesome.

Further, in the case of a data editing program such as a spreadsheet processing program that reads out a large amount of data at the same time and updates it, a large amount of data is locked at the same time, so that a collaborative work is required. Due to this, when creating a document or performing statistical processing, it sometimes took a long time to release all the data lock states.

Further, when the user A forgets to release the locked state in the data edit processing program, the user B of the data edit processing program in the lock release waiting state continues after the locked state continues for a long time. There is also a problem in that the user A must be requested to release the lock by using the above means.

As described above, in the conventional data processing system, the lock mechanism for accessing the database is realized by the lock / unlock operation in the database management system, so that, for example, a large number of users share With an application program that edits data of documents and drawings with, there is a disadvantage that the operability of the user is reduced or the method of access right control cannot be easily changed depending on the type and characteristics of the application program. It wasn't valid.

[0010]

As described above, in the conventional data processing system, it is difficult to use an existing program as a user interface as it is, and it is necessary to change or recompile the program. The present invention has been made in view of the above circumstances,
A first object is to provide a data processing system that can be used as a user interface without changing or recompiling an existing program.

On the other hand, in the conventional data processing system, since it is not possible to finely control the access right, the user has a heavy burden in terms of operability. The present invention has been made in view of the above circumstances, and it is a second object of the present invention to provide a data processing system capable of controlling an access right according to a situation and improving the operability of a user. To aim.

[0012]

In order to achieve the first object, the data processing system of the present invention (Claim 1) comprises:
Data storing means for storing data, at least one data operating means for operating the data to be stored in the data storing means, and the data operating means are provided corresponding to the data operating means, respectively. The status of the operation to be performed on the data is monitored, and the data operating means instead executes the operation to be executed on the data storing means according to the result of the monitoring, and the data operating means and the data storing means. And a data operation proxy means for transmitting and receiving data relating to the operation.

Preferably, the data operation proxy means is
You may implement | achieve as an object prepared corresponding to a data operating means in the virtual object world constructed in the computer group. This means that the data operation surrogate means is executed by a program different from the data operation means.

Further, the data processing system may further be provided with a data processing means for processing the data and the data operation proxy means corresponding to the data processing means. Further, processing result storage means for storing processing results by the data processing means and the data operation proxy means corresponding to the processing result storage means may be further provided.

On the other hand, in order to achieve the second object, the data processing system of the present invention (claim 2) is an input means for inputting data and a data storage means for storing the data input by the input means. A data editing processing means for editing data stored in the data storage means by each data editing application program, and a data status storing the data editing status in the data editing processing means The storage means controls reading and writing of data edited by the data editing application program with respect to the data storing means, and when the content of the data state storing means changes due to data editing by an arbitrary data editing application program, Notifying the other data editing application program of the change information, Characterized by comprising a data change control means for controlling access to said data storage means in the ram.

[0016]

According to the data processing system of the present invention (Claim 1), the data operation surrogate means corresponding to the data operation means (for example, the user interface or the data processing device) is:
The operation desired by the data operating means is monitored, and the operation for the data storing means is executed in place of the data operating means.

By doing so, the existing data manipulation means can be used without changing or recompiling the program. Further, when adding a new data operation means, it is only necessary to add the corresponding data operation proxy means, and it is not necessary to change the existing data operation proxy means.

On the other hand, according to the data processing system of the present invention (claim 2), one user alternately edits one data by using two different data editing application programs under the environment of the multi-window system. Even in such a case, the access right to the data storage means in each data editing application program can be controlled by notifying other data editing application programs of the change information by the data editing in one data editing application program. Therefore, the operability for the user can be improved.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. This embodiment assumes a data processing system in which a plurality of user interfaces (for example, editors) may simultaneously operate the same data (file) stored in the file means. The first embodiment and the second embodiment relate to improvement of a part of the user interface, and describe a data processing system capable of using a new user interface without changing the program or recompiling. . Further, the second to fifth embodiments relate to the improvement of the data management function part, and it is possible to perform fine access right control according to the situation and to improve the operability by the user. The data processing system will be described.

(First Embodiment) First, a data processing system according to a first embodiment of the present invention will be described. FIG. 1 shows a data processing system according to the first embodiment of the present invention.
This data processing system is vi101, which is an editor program for a user to operate data.
Vi communication means 10 connected to 101
2, vi object (data operation proxy means) provided corresponding to this vi communication means 102
01, an editor program emacs111, an emacs communication unit 112 connected to the emacs111, an emacs object (data operation proxy unit) 211 provided corresponding to the emacs communication unit 112, the vi object 201, and the emacs object 211. Data exchange / management objects (group) 221 and data processing / management objects (group) 2 each of which is used for exchanging messages.
Screens 10 for users of vi, each connected to 21
3 and emacs user screen 113, and a file means (data storage means) 120 connected to the data processing / management object (group) 221. Further, vi 101, vi communication means 102, emacs 111, emacs communication means 112, screen 103, screen 113 and file means 120 exist in the real world, whereas vi object 201, emacs object 211, data processing / management. Object (group) (hereinafter,
A data processing / management unit 221 exists in the object world 200. Note that 202,
212 and 222 are threads.

The vi object 2 which is a feature of this embodiment
01 monitors the vi communication unit 102 connected to the vi 101 at all times or at a predetermined timing, so that the vi 101 grasps the content of the operation to be performed on the data stored in the file unit 120, and the vi 101 executes the operation. Instead, it does what it should do. In addition, the exchange of data regarding operations to act on behalf of
This is done via the vi communication means 102.
The operation status is monitored by, for example, looking at the update time or contents of a predetermined file in the vi communication means 102, or by detecting a signal indicating that a change has been made. As a result, vi101
From the perspective, the vi object 201 does not exist,
Since it is the same as manipulating the data in the communication means 102, there is no need to change the program of the vi 101. The same applies to the emacs object 211.

The process flow of this embodiment will be described below. In this embodiment, it is assumed that two users jointly edit a character string in a file by using editor programs vi101 and emacs111 as user interfaces. vi101,
Both the emacs 111 have communication means 102 and 112 for reading and writing files with the outside world. Here, the user U1 writes the data D in the file means.
1 is operated by vi101, and the user U2 operates the same data D1 by emacs111. FIG. 2 shows the data processing / management means 2 in this embodiment.
21, the processing flow of the vi objects 201 and vi101, and the relationship between them are shown.

<Processing Flow of Data Processing / Management Unit 221> First, when the user U1 issues a request to edit the data D1, the data processing / management unit 221 receives the request (step S101), and the vi object 201 is displayed. It calls (step S102). The user's request may be a command from the keyboard, or may be a mouse click on the display portion corresponding to D1 displayed on the screen (screen 103 or another screen not shown).

Next, the data D1 is sent from the file means 120.
Is read (step S103), and D1 is transmitted as a message to the vi object 201 (step S1).
04). Since the vi object 201 transmits the change of D1 as a message, it waits for this message (step S105). When the message arrives, the changed D1 is written to the file means 120 (step S106) and simultaneously displayed on the screen 113 (step S).
107).

<Flow of processing of vi object 201>
The vi object 201 activates vi101 (step S111). This startup process includes vi101
It may also include additional processing such as opening a new window for. Next, a file (file for communication) used by the vi 101 as the communication means 102 is designated (step S11).
2). If UNIX, / tmp / D1. It may be a file such as tmp.

Then, the message from the data processing / management means 221 is waited for (step S113), and when the message D1 arrives, it is written in the communication file (step S114). Then, monitor whether this file has been updated (step S
115), when it is updated, the new content D1 is read (steps S116 to S117), and this is transmitted as a message to the data processing / management means 221 (step S118).

<Processing Flow of vi101> The vi101 only performs normal file editing. That is, D1 is read from the file for communication (step S121), D1 is edited (step S122),
D1 is written in the file for communication (step S123), the above operation is repeated successively, and when the editing is completed (step S124), the editing ending process is performed (step S125).

In the process of ending the editing, for example, UN
In the case of IX, the signal is transmitted to the parent (in this example, the vi object 201 or the window shell, etc.) by returning. The parent uses this signal to terminate itself, but it is omitted from FIG. 2 here because it is complicated. On the other hand, the user U2 uses the emacs111
Therefore, the same processing may be performed with the portion of vi101 as emacs111. Since the emacs 111 has a function of performing finer control using a file called .emacs at the user level, it is possible to use this.

Here, in this embodiment, when it is desired to add a new user interface unit, an object corresponding to the new user interface unit may be newly added to the object world. For example, if there is only a user interface means vi and emacs until now, and a third user interface means different from these is to be added, it is almost the same as the vi object 201 and at least names vi and e.
All that is required is to prepare an object that has been changed from macs to the one corresponding to the third user interface means.
Also, if necessary, the vi communication means 102
A third communication means corresponding to the third user interface means having the same function as
You may prepare the communication means of. It is not necessary to change the existing object.

Further, in the case of adding a thing having a function of performing a peculiar control such as emacs, it can be dealt with by adding the part to the object. Further, when a new data processing / management function is required, the data processing / management means 221 in the object world is used.
Should be changed. Further, the data processing / management means 2
A processing result storage unit for storing the processing result of 21 and an object corresponding to the processing result storage unit may be further provided.

As described above, in this embodiment, by providing the data operation proxy means such as the vi object and the emacs object, the existing user interface means such as vi and emacs can be used without changing the program at all. It can be used to build a new data processing system.

(Second Embodiment) Next, an embodiment in which a new device is added to the data processing system will be described. FIG. 3 is a diagram showing the correspondence between devices and objects. That is, in the first embodiment, the user interface means such as vi101 or emacs111 has been described as the means for manipulating the data, but in the present embodiment, the data processing means such as the personal information device or the PC is the means for manipulating the data. Is to handle. It should be noted that household appliances can also be treated as data processing equipment as long as they include a function of manipulating data.

As shown in FIG. 3, in this embodiment, the OA device 321, the PC / WS / server 322, and the personal device 323 exist in the real world, and the object world 300
Is provided with objects (data operation proxy means) 301, 302, 303 corresponding to the OA device 321, the PC / WS / server 322 and the personal device 323, respectively, and the objects 301, 302, 303 are mutually connected. Messages are exchanged. 311 to 314
Is a thread.

Also in this embodiment, as in the case of the first embodiment, the objects 301, 302, 303 act on behalf of the data operations of the devices 321, 322, 323 corresponding to the objects 301, 302, 323, respectively. , 303 exchange messages between the corresponding devices 321, 322,
Data is exchanged between 323. Further, when it is desired to newly connect the home electric appliance 324 to the data processing system of FIG. 3, it is sufficient to provide the object 304 corresponding to the home electric appliance 324 in the object world 300.

FIG. 4 is a diagram showing an example of a method for realizing this embodiment. As shown, at the bottom layer is the hardware 400, 403. Specifically, these are data processing devices such as personal information devices and PCs. CPU
Although 402 and 405 are CPUs in the devices 400 and 403, one device does not necessarily have to correspond to one CPU. Storage means 401, 404
Is generally an IC memory, but may be a core memory, a magnetic disk, or a card memory.

The central layer is the kernel layer, which is the basic part of the OS. Here, the thread 41 that is the execution subject
0, 411, 412 and the virtual storage means 406,
407, 408 and 409 are prepared. The origin of these means is hardware. Threads 410, 41
1, 412 are created by dividing the CPU execution time. Virtual storage means 406, 407, 408, 409
Is created by dividing the memory or disk area. U
In the NIX example, threads are processes and virtualized storage means are files or virtual storage. These may be threads and shared memory in another OS.

The top layer is the layer of the object world. The objects 413, 414, 415 are composed of threads 410, 411, 412 and virtual storage means 406, 4.
It is created by combining 07, 408 and 409. The message exchange of the objects 413, 414, 415 corresponds to the communication of the devices 400, 403 in the real world. In other words, the fact that a message is transmitted from the object 413 to the object 415 means that the object 4
That is, information is communicated from the device 400 corresponding to 13 to the device 403 corresponding to the object 415. Therefore, it is not necessary to consider the difference in communication means when creating the application program, and the same program can be used for devices using different communication means.

(Third Embodiment) FIG. 5 shows a schematic configuration of a data processing system according to a third embodiment of the present invention. As shown in the figure, this data processing system includes an input unit 11, an output unit 12, an input / output management unit 13, a data edit processing unit 14,

The input / output management unit 13 displays / controls an input window and an output window of data as in a multi-window system, and a data edit processing unit 1 receives a request for starting an application program input by a user.
It is supposed to be given to 4.

The data edit processing unit 14 is for editing sentences, figures and statistical data stored in the data storage unit 15 which is a database management system, and is used for editing data such as text editors, graphic editors and spreadsheet programs. It is composed of application programs 14 ₁ , 14 ₂ , ..., 14 _n . In this case, the data editing application program 1
4 ₁ , 14 ₂ , ..., 14 _n are also applied to a case in which two different text editors are simultaneously used for certain text data.

A data update processing control unit 16 is connected to the data storage unit 15. This data update processing control unit 1
6 reads various data from the data storage unit 15 in response to a request from the data edit processing unit 14 to read the data edit processing unit 1
4 is passed to the data editing application programs 14 ₁ and 14 ₂ and the data edited by the data editing application programs 14 ₁ and 14 ₂ is written back to the data storage unit 14. Further, the data update processing control unit 16
When reading / writing these data, the data status storage unit 17 displays the display / editing status of each data, the information of the user and the workstation being used, the application program used for the display / editing and the information about the window position thereof. I am writing to Further, the data update processing control unit 16 refers to the data state storage unit 17 and refers to a plurality of users and a plurality of data editing application programs 1
Control is performed to maintain consistency of data update by 4 ₁ and 14 ₂ . For example, when a certain data is edited by the data editing application program 14 ₁ , the change information in the data state storage section 17 is simultaneously transmitted to the data editing application program 14 ₂ being displayed or being edited.

FIG. 6 shows an example of stored information in the data state storage unit 17, in which a user name, a used workstation name, an application program name, etc. are stored. Next, as a specific example, a data update process will be described. First, as shown in FIG. 7, one user (U1) 3
1 from the workstation 1 (W1) 32, two "application programs", that is, the edit processing program 1 (P
1) 33 and the edit processing program 2 (P2) 34 are controlled by the data update processing control unit 35, and one “figure A (D) in the document data 1 (D1) in the database 1 (B1) 36 The case of displaying and editing "F1)" almost simultaneously will be described.

In this case, the document data 1 (D1) in the database 1 (B1) 36 is accessed by any application program, that is, the edit processing program 1 (P1) 33 and the edit processing program 2 (P2) 34. It has not been done. From this state, in FIG. 8 and FIG.

First, in step (1), at the workstation 1 (W1) 32, the user 1 (U1) 31 issues an instruction to activate the edit processing program 1 (P1) 33 (for example, a layout editor for desktop publishing). When executed, the edit processing program 1 (P1) 33
Is started.

Next, in step (2), the user 1 (U
1) 31 tries to display the document data 1 (D1) on the edit processing program 1 (P1) 33, the edit processing program 1 (P1) 33 instructs the data update processing control unit 35 to "document data 1 (D1)". D1) read request "is transmitted.

The data update processing control unit 35 indicates from the state storage table shown in FIG. 10 that "the document data 1 (D1) and the data belonging to the document data 1 (D1) are not in the edit state from any application program". Check. Here, “Document data 1 (D1) is edited by the editing processing program 1
(P1) 33 ”, it is possible to display the document data 1 (D1) from the database 1 (B1) 36 and the data belonging to the document data 1 (D1) (in this description,
For example, FIG. A (F1) is read out) and transmitted to the edit processing program 1 (P1) 33. Then, as shown in the column after (2) in FIG. 10, “document data 1 (D1) and data belonging to the document data 1 (D1) (for example, FIG. A (F1)) are stored in the edit processing program 1 ( P1) 33, display start ”is stored. At this time, the time T2 is also stored. The data received by the edit processing program 1 (P1) 33 is displayed in the display mode.

Next, in step (3), the user 1 (U
1) In order to partially correct the view A (F1) in the document data 1 (D1) in which 31 is already displayed, the graphic data editing menu of the edit processing program 1 (P1) 33 causes the document data 1 (D1) When the shift to the edit mode is instructed, the data update processing control unit 35 detects that the application program of FIG. A (F1) is "not in edit state" from any application program, 1 (P1) 33 ”, and“ the edit processing program 1 (P1) 33 shown in FIG. A (F1) at the time T2 exists in the state storage table as shown in the column after (3) in FIG. "Start display by" is displayed at time T3 in FIG.
1) 33, "edit start" and then the edit processing program 1 (P1) 33 returns a response of "edit start permission".

Next, in step (4), when the user (U1) 31 performs the update operation of FIG. A (F1) after the modification of FIG. A (F1) in the editing processing program 1 (P1) 33 is completed. The edit processing program 1 (P1) 33 requests the data update processing control unit 35 to write the data shown in FIG. A (F1).

Then, the edit processing program 1 (P1) 3
3 is the database 1 (B1) for the data of FIG. A (F1)
In addition to writing the data to the memory 36, the data stored in the state storage table as shown in the column after (4) in FIG.
1) is edited by the edit processing program 1 (P1) 33 "
"At time T4, Fig. A (F1) shows the edit processing program 1
(P1) Edited by 33 "is updated.

Next, in step (5), the user 1 (U
1) 31 newly tries to edit FIG. A (F1) using the edit processing program 2 (P2) 34, and gives an instruction to start the edit processing program 2 (P2) 34.

Here, the workstation 1 (W1) 3
2, when a new edit processing program 2 (P2) 34 is started, the edit processing program 1 (P1) 33 sends a message to the user 1 (P1) 33 to the edit processing program 1 (P1) 33 itself through an operating system or a window system. [U1) Operation interruption by 31 ”is detected, and the writing of FIG. A (F1) currently being edited is performed by the data update processing control unit 3
Request to 5.

Then, the data update processing control unit 35
When (F1) is written and a completion notification is returned to the user 1 (U1) 31, the data update processing control unit 35 is notified again of “temporary interruption of editing in FIG. A (F1)”. As a result, the data update processing control unit 35 displays “at time T5 in FIG.
The fact that (F1) has been interrupted by the editing processing program 1 (P1) 33 is stored in the state storage table as shown in the column after (5) in FIG.

Next, in step (6), the user 1 (U
1) 31 is the edit processing program 2 (P2) 34 and is shown in FIG.
When the editing of (F1) is instructed, the editing processing program 2
(P2) 34 is sent to the data update processing control unit 35 as shown in FIG.
Send the read request of 1).

Then, the data update processing control unit 35 "3
“0” means that “Edit A (F1) in FIG. A (F1) is interrupted by the edit processing program 1 (P1) 33 at time T5” in the state storage table, and then the database 1 (B1) 3
FIG. A (F1) is read from 6 and the fact that “figure A (F1) starts editing at time T6 by editing processing program 2 (P2) 34” is stored as shown in the column after (6) in FIG. Edit the data of Fig. A (F1) by editing processing program 2 (P2) 3
Send to 4.

Then, in step (7), the user 1
When the (U1) 31 tries to restart the edit processing program 1 (P1) 33, which has suspended the temporary editing, the edit processing program 2 (P2) 34 sends a "user 1 (U1)" message to itself.
"Operation interruption by 31" is detected, the "write request of FIG. A (F1)" is issued to the data update processing control unit 35, and the data update processing control unit 35 writes "FIG. A (F1)" to the database 1 (B1) 36. Writing ”, and further, as shown in the column after (7) in FIG. 10, the state storage table stores“ T7 in FIG. A (F1) edit interrupted by edit processing program 2 (P2) 34 ”. At the same time, the edit processing program 1 (P1) 33 detects “restart execution” and notifies the data update processing control unit 35 of “restart editing of FIG. A (F1)”, and the data update processing control unit 35 is stored. “At time T5, editing is interrupted by editing processing program 1 (P1) 33 in FIG. A (F1)” is deleted.

As described above, by controlling the display / editing state of data under the control of the data update processing control unit 35, access by the edit processing program 1 (P1) 33 and the edit processing program 2 (P2) 34 is performed. It becomes possible to avoid the collision.

Therefore, in this way, conventionally, when a certain data editing application program starts to display and edit document data, access to the corresponding data is locked until the work is completely completed, and other data editing is performed. It is not accessible from the application program, and it is not convenient when one user edits a document using multiple data editing application programs. However, the display and editing of data in the data editing application program is not convenient. By notifying other related data editing application programs of the state of, the finer lock control can be performed, so that the collision of access can be reduced and the usability for the user can be improved.

Further, by using the information about each data as shown in FIG. 6, when the display / editing is restarted, for example, the previous usage environment (user, workstation used, application program, window display position, etc.) A combined usage environment can also be provided.

(Fourth Embodiment) Next, as shown in FIG. 11, one user (U1) 71 works on the workstation 1.
From (W1) 72, two “application programs”, that is, the edit processing program 1 (P1) 73 and the edit processing program 2 (P2) 74, are used to control the database 1 (B1) 76 by the control of the data update processing control unit 75. The two "Figure A (F) in the document data 1 (D1)
1) and FIG. B (F2) "are displayed and edited almost at the same time.

In this case, the document data 1 (D1) and the document data 1 in the database 1 (B1) 36
It is assumed that FIG. A (F1) belonging to (D1) is not accessed from any of the application programs, that is, the edit processing program 1 (P1) 73 and the edit processing program 2 (P2) 74. From this state, FIG. 12 and FIG.
3, first, in step (1), as in step (1) of the third embodiment, the edit processing program 1
(P1) 73 is activated.

Next, in step (2), the edit processing program 1 is executed in the same manner as in step (3) of the third embodiment.
(P1) 73 starts to edit FIG. A (F1). next,
In step (3), when the user (U1) 71 instructs the edit processing program 1 (P1) 73 to edit FIG. B (F2), the edit processing program 1 (P1) 7
3 first requests the data update processing control unit 75 to write FIG. A (F1) being edited until then, and the data update processing control unit 75 writes the data in the database 1 (B1) 76, and then the edit processing program 1 (P1). ) 73 to notify the completion.

The edit processing program 1 (P1) 73 causes the data update processing control unit 7 to perform the temporary interruption of the edit in FIG.
5, the data update processing control unit 75 stores that the editing processing program 1 (P1) 73 has temporarily suspended the editing of FIG. A (F1). Then, this time, the edit processing program 1 (P1) 73 issues the edit request of FIG. B (F2) in the same manner as in step (2), and enters the edit mode of FIG. B (F2).

Next, in step (4), as in step (5) of the third embodiment, the edit processing program 2
(P2) 74 is activated. Then, in step (5), as in step (5) of the third embodiment, the edit processing program 2 (P2) 74 causes FIG. B (F2) to enter the edit mode. Note that in such an operation, the contents stored in the state storage table of the data update processing control unit 75 change as shown in the columns after (2) to (5) in FIG.

Therefore, in this way, in the conventional case,
Since the consistency of data is controlled by simply operating “lock” and “unlock”, one application program may lock other data while locking other data. And even if it is by one user, notice the lock by the former editor only after moving from one editor to the other,
There was a case where once I went back to the former editor to unlock the data, and then performed the lock / edit operation with the editor in the school building, "in editing" or "temporarily suspending editing" for each individual data. Is managed, it is possible to perform finer control regarding data locking. This is also effective when the data is accessed by multiple users.

(Fifth Embodiment) Next, two users (U
1) 1111 and user (U2) 1112 respectively from workstation 1 (W1) 1121 and workstation 1 (W2) 1122, two edit processing programs 1 (P11) 1131 and edit processing program 2 ( P12) 1132 and the edit processing program 1 (P12)
21) 1141, edit processing program 2 (P22) 11
Document data 1 in the database 1 (B1) 116 under the control of the data update processing control unit 115
The two "Figure A (F1) and Figure B (F
2) ”is displayed and edited almost simultaneously.

In this case, in FIG. 16 and FIG.
First, in step (1), the workstation 1 (W1) is operated in the same manner as in step (1) of the fourth embodiment.
At 1121, the user (U1) 1111 activates the edit processing program 1 (P11) 1131. Next, in step (2), as in step (2) of the fourth embodiment, the edit processing program 1 (P11).
1131 starts editing FIG. A (F1). in this case,
The stored contents of the state storage table are as shown in the column after (2) in FIG.

Next, in step (3), the edit processing program 1 is executed in the same manner as in step (3) of the fourth embodiment.
(P11) 1131 suspends the editing of FIG. A (F1) and starts the editing of FIG. B (F2). In this case, the stored contents of the state storage table are as shown in the column after (3) in FIG.

Next, in step (4), the workstation 1 (W) is used as in step (1) of the fourth embodiment.
2) At 1122, the user (U2) 1112 activates the edit processing program 1 (P21) 1141.
In this case, the contents stored in the state storage table 17 are as shown in FIG.
It becomes as shown in the column after (4) of. Then, in step (5), when the user (U2) 1112 instructs the editing processing program 1 (P21) 1141 to edit FIG. A (F1), the editing processing program 1 (P2)
1) 1141 transmits a “edit start request in FIG. A (F1)” to the data update processing control unit 115.

Then, in the data update processing control unit 115, "FIG. A (F1) indicates time T2 in the state storage table 17.
It is detected that "editing has been started by the user (U1) 1111" but "time T3 and its editing are interrupted", and "Figure A (F1) is edited by the editing processing program 1 (P21)."
1141 is editable ". And in FIG.
(5) As shown in the following column, the status memory table displays “Figure A (F
1) edit processing is started by the edit processing program 1 (P21) 1141 ", and the edit processing program 1 (P21) is stored.
1141 is permitted to start editing.

Next, in step (6), the user (U2)
When 1112 instructs the edit processing program 1 (P21) 1141 to edit FIG. B (F2), the edit processing program 1 (P21) 1141 instructs the data update processing control unit 115 to “FIG. ) Edit start request ”. In the data update processing control unit 115,
“Figure B (F2) is the edit processing program 1 of the workstation 1 (W1) 1121 from the“ state storage table ”
(P11) 1131 detects that "Editing" is performed, and "Fig. B (F2) is edited by editing processing program 1 (P21)
In step 1141, it is determined that the editing cannot be performed ”, and the editing start program is not permitted to the editing processing program 1 (P21) 1141.

Edit processing program 1 (P21) 1141
Then, the “display start request of FIG. B (F2)” is transmitted again, and the data update processing control unit 115 causes the data update processing control unit 115 of FIG.
(6) The status memory table is updated as shown in the following column,
Data is transmitted to the edit processing program 1 (P21) 1141 and the display mode is shown in FIG. B (F2).

Next, in step (7), the user (U
1) Edit processing program 1 (P11) by 1111
When the end of 1131 is instructed, the edit processing program 1
(P11) 1131 writes FIG. B (F2) being edited, and the data update processing control unit 115 updates the state storage table 17 of FIG. At this time, the state storage table 17
From this point, all the entries related to the edit processing program 1 (P11) 1131 are deleted. In this case, the stored contents of the state storage table are as shown in the column (7) of FIG.

Then, in step (8), the user (U
2) 1112 is edit processing program 1 (P21) 114
If the user again requests "start editing of FIG. B (F2)" to 1, the edit processing program 1 (P21) 1141 will edit the FIG. B (F2) in the same manner as in step (3) of the third embodiment. Start. In this case, the stored contents of the state storage table are as shown in the column after (8) in FIG.

Therefore, in this way, the lock / unlock control can be performed even for the access by a plurality of users. For example, even when an editing request is issued from the user (U2) 1112 during the editing of the user (U1) 1111 in FIG. A (F1) in step (6), the editing processing program 1 by the data update processing control unit 115 is executed.
The control of the data update processing control unit 115 also controls to forcibly write the figure A (F1) to (P11) 1131 and forcibly transfer the editing right to the editing processing program 1 (P21) 1141. Can be realized by Further, the present invention is not limited to the above-mentioned embodiments, and can be appropriately modified and carried out without changing the gist.
