Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an exclusive control device, a program, and a method for processing files shared by each other by a plurality of users.
[0002]
[Prior art]
Conventionally, in a distributed processing system, a client server system, or the like, partial exclusive control of a shared file is performed. As one example, exclusive control in units of transactions in a database and exclusive control in units of objects in a file in a collaborative work using a CASE tool (computer aided software engineering tool) are known.
[0003]
For example, in the exclusive control of the client server system, when a procedure for an object of a shared file is executed by a request from a client, a flag for prohibiting execution of the procedure in response to a request from another client is set for the object. When the flag is set in this way, that is, when the exclusive ownership of the client for the object is set, the period until the flag is reset (exclusive control period), other clients, that is, clients without ownership, Objects with flags set cannot be processed.
[0004]
[Problems to be solved by the invention]
If the exclusion control period is short, it does not cause a big problem.However, when the start and end of the exclusion control period are not automatically determined according to the critical section, but determined by the client user's will, the exclusion control is performed. The period is easily prolonged.
[0005]
However, during the exclusive control period, a user who does not have ownership of an object that is under exclusive control is transferred from the user with exclusive ownership to himself without knowing when the ownership is set to himself. You have to wait until the rights are transferred. Therefore, when the exclusive control period is prolonged, there is a problem in terms of a reduction in the resource operation rate and a reduction in the user's work efficiency when viewed in a plurality of systems that process shared files.
[0006]
The present invention has been created to solve such a problem, and an object of the present invention is to provide an exclusive control device, a program, and a method capable of efficiently processing a file shared with each other by a plurality of users. I do.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an exclusive control device according to the present invention includes an ownership management unit that sets a user's ownership for each object in a file, and prohibits a user who does not own the object from processing the object. Exclusive control means, and proprietary dialogue means for requesting and granting ownership to the remote user. The possession dialogue means implements a function of requesting the ownership of the remote user and permitting the ownership of the ownership from the remote user. For this reason, a user who does not own the object to be processed in the future requests the other user who owns the ownership to transfer the ownership to himself, and transfers the ownership from the other user. By having them, they can get the ownership earlier than if they simply wait passively until the ownership is transferred to themselves. Therefore, according to the exclusive control device of the present invention, a file shared with each other can be efficiently processed by a plurality of users.
[0008]
Further, the exclusive control device according to the present invention is further characterized by further comprising status guide means for enabling a user to identify an inconsistent state of the object before the synchronous update. Non-owning users of an object may know that an object will be changed by future synchronous updates, allowing for smooth collaboration by multiple users.
[0009]
Further, the exclusive control device according to the present invention is further characterized by further comprising update dialogue means for requesting and permitting a remote user to perform synchronous update on an object for which ownership is set. A plurality of users who process shared files, because it is possible to execute a synchronous update only after the permission of another user has been obtained, instead of performing an unconditional synchronous update on the processing performed on an object performed by a certain user The whole unified processing becomes possible.
[0010]
Further, the ownership management means of the exclusive control device according to the present invention is characterized in that the ownership of a user is set in units of a second type object corresponding to control information of processing on a first type object. Thus, for example, while setting the ownership for processing a certain object to a certain user, and setting the ownership for processing control information for outputting the object to another user, a detailed Ownership can be set. Specifically, for example, it is possible to perform a collaborative work in which an editor of sound source data itself such as a sound source waveform and an editor of output conditions such as a balance setting of a reproduction volume of a plurality of sound source data are individually set.
[0011]
Each function of the plurality of means provided in the exclusive control device according to the present invention is realized by an arbitrary combination of hardware resources whose functions are specified by the configuration itself and hardware resources whose functions are specified by a program. . The functions of the plurality of means are not limited to those realized by hardware resources which are physically independent of each other.
[0012]
Further, the present invention can be specified not only as an invention of an apparatus, but also as an invention of a program, an invention of a recording medium on which the program is recorded, and an invention of a method.

As shown in the figure, the status information “Owned:“ User name of billing source remote user ”” is displayed.
[0031]
The screen controlled by the interactive process has been described above. Hereinafter, the file 30 stored in the hard disk 14 of the exclusive control device 1a is shared by the user of the exclusive control device 1a and the user of the exclusive control device 1b, and the information stored in the exclusive control device 1a and stored in the exclusive control device 1b. A case will be described as an example where the file 30 is edited jointly while synchronizing the received information. The following processing is performed when the CPU 11 of the data editing apparatus 1 loads the data editing program 2 into the RAM 13 and executes it.
[0032]
FIG. 17 is a sequence diagram illustrating a flow of a process of requesting and granting a new ownership setting when the object is not owned by another user. When the local user performs an operation of claiming ownership, the data editing apparatus 1 transmits the identification information of the billing object and the identification information of the billing source user to the data editing apparatuses 1 of all the remote users, and claims the ownership. (S105). Specifically, for example, the processing is performed as follows. The interactive process of the data editing device 1a outputs ("object information", "ownership request") to the relay process when the user performs an operation to request ownership on the data screen 28 or the operation screen 29. The relay process of the data editing device 1a transmits ("object information", "ownership request", "user name of the data editing device 1a") to all the data editing devices 1 including the data editing device 1b.
[0033]
Upon receiving a request for transfer of ownership from the remote user, the data editing apparatus 1 informs the local user of the request for ownership by display or sound (S110). Specifically, for example, the processing is performed as follows. When the relay process of the data editing device 1b receives (“object information”, “ownership request”, “user name of the data editing device 1a”) from the data editing device 1a, it outputs the information to the interactive process. . The interactive process of the data editing device 1b changes the color of the portion displaying the object on the data screen 28 or the operation screen 29, and displays “ownership request:“ user name of the data editing device 1a ”” at that portion. I do.
[0034]
When the local user whose ownership is requested by the remote user performs an operation of granting the new ownership, the data editing apparatus 1 notifies the requesting remote user that the permission has been granted by the local user (S115). Specifically, for example, the processing is performed as follows. The interactive process of the data editing device 1b outputs ("object information", "ownership") to the relay process when the local user performs an operation to grant ownership. The relay process of the data editing device 1b transmits (“object information”, “ownership permission”, “user name of the data editing device 1b”) to the data editing device 1a.
[0035]
When notified of the permission from all the billing remote users, the data editing apparatus 1 of the billing source user sets the ownership to the local user for the local attribute data 32 of the object for which the ownership is claimed by The local user can process the object, notify all the remote users that the ownership has been set to the local user, and synchronously update the attribute data in the data editing apparatus 1 of all the users (S120). . Specifically, for example, the processing is performed as follows. When the relay process of the data editing device 1a receives (“object information”, “ownership license”, “user name of the data editing device 1”) from the data editing devices 1 of all remote users including the data editing device 1b , (“Object information”, “ownership update”, “user name of data editing apparatus 1a”) as an argument to call the attribute update process, and to all remote user data editing apparatuses 1 (“object information”, “ownership update”). "," The user name of the data editing apparatus 1a "). In all data editing apparatuses 1, the attribute update process sets the owner of the attribute data 32 of the object specified by the object information to the user name of the data editing apparatus 1a. In the data editing device 1 of all users, the interactive process displays “in possession:“ user name of data editing device 1a ”” for the object based on the attribute data.
[0036]
FIG. 18 is a sequence diagram illustrating a flow of a process in which a user processes an object.
When the user performs an operation for processing an object, the data editing apparatus 1 prohibits the processing when the local user has no ownership of the object (S205). Specifically, for example, it is prohibited as follows. When an object is selected by a mouse or the like, the interactive process of the data editing device 1b acquires the user name of the user whose ownership is set for the object from the attribute data 32 via the relay process, and sets the ownership. The user name of the entered user is compared with the user name of the local user. If the user names do not match, the interactive process refuses to enter update data for the selected object and outputs, for example, an error message, an error sound, and the like.
[0037]
When the ownership of the object is set to the local user, the data editing apparatus 1 allows the local user to perform processing. When the object is edited by the local user, the data editing apparatus 1 stores update data (S210), and the object is edited. Is notified to all the remote users, and the synchronous update flag is set to 1 in the data editing apparatuses 1 of all the users (S215). More specifically, for example, when the local user performs an operation of processing an object and inputs update data, the interactive process of the data editing apparatus 1a enters (“the object information”, “edited” ") Is output. In the editing process, the update data is stored in the RAM 13. Here, the operation of processing the object means inputting data from the keyboard or moving the volume knob 40 up and down. The relay process of the data editing device 1a transmits (“the object information”, “edited”) to all the data editing devices 1 including the data editing device 1b. For the attribute data 32 of the object specified by the information, the synchronous update flag is set to 1. In the data editing apparatuses 1 of all the users, when the synchronous update flag is set to 1, the interactive process determines that the object is "owned: The display of "user name of data editing apparatus 1a" is changed to "edited:" user name of data editing apparatus 1a "".
[0038]
The local user's data editing apparatus 1 may notify the remote user of the update data every time the local user performs a processing operation or at regular intervals. Further, the data editing device 1 of the remote user may display the update data notified about the object without updating the edit data of the object with the update data.
[0039]
FIG. 19 is a sequence diagram illustrating a flow of a process of requesting and granting a synchronous update to another user. When the operation of requesting the synchronous update is performed by the local user, the data editing device 1 requests the synchronous updating to the data editing devices 1 of all the remote users (S305). Specifically, for example, the processing is performed as follows. The interactive process of the data editing apparatus 1a of the user who has processed the local editing data, when an operation for requesting an update on the processed object is performed, ("object information", "synchronous update request", "update data"). Output to the relay process. Update data is output from the editing process. The relay process of the data editing device 1a transmits the information to the data editing devices 1 of all the remote users including the data editing device 1b.
[0040]
Upon receiving a request for a synchronous update from the remote user, the data editing device 1 informs the local user of the request for the synchronous update by display or sound (S310). Specifically, for example, the processing is performed as follows. When the relay process receives (“object information”, “synchronous update request”, “update data”) from the data editing device 1a, it outputs (“object information”, “synchronous update request”) to the interactive process. The interactive process changes the color of the part displaying the object uniquely identified by the object information, and displays “update request:“ user name of data editing device 1a ”” for that part. Also, the update data is displayed for the object without updating the edit data of the object with the update data so that the object can be returned to the original state when the object is not updated.
[0041]
When the local user requested to perform the synchronous update by the remote user performs an operation of permitting the synchronous update, the data editing apparatus 1 notifies the remote user of the request that the local user has been granted the synchronous update (S315). Specifically, for example, the processing is performed as follows. The interactive process of the data editing device 1b outputs ("object information", "synchronization update permission") to the relay process when the local user performs an operation to permit synchronization update. When the relay process of the data editing device 1b outputs (“object information”, “synchronization update permission”) from the interactive process, it outputs “(object information”, “synchronization update permission”, “user name of the data editing device 1b” ") To the data editing device 1a.
[0042]
When the synchronous update is permitted by all the remote users, the data editing device 1 of the requesting user of the synchronous update updates the local object with the update data, and simultaneously updates the local object with the data editing device 1 of all the remote users. Then, the editing data and the attribute data are synchronously updated in the data editing apparatuses 1 of all the users (S320). Specifically, for example, the processing is performed as follows. When the relay process of the data editing device 1a receives (“object information”, “synchronization update permission”) from the data editing devices 1 of all remote users including the data editing device 1b, the relay process (“object information”, “update Invoke the update process with data ") as an argument. The update process updates an object uniquely identified by the object information with the update data passed as an argument and resets a synchronous update flag of the attribute data. The interactive process of all the data editing apparatuses 1 displays “in possession:“ user name of the data editing apparatus 1a ”” for the object on the data screen 28 or the operation screen 29.
[0043]
FIG. 1 shows that when ownership of an object is set to the user of the data editing device 1a, the ownership of the object (owner of the data editing device 1b) is set, that is, transferred to the user who is the owner of the object. FIG. 9 is a sequence diagram illustrating a flow of a process of requesting and granting a request.
[0044]
When the local user performs an operation for requesting the transfer of the ownership of the object for which the ownership is already set to the remote user, the data editing apparatus 1 compares the identification information of the billing object and the identification information of the billing user with the remote user. The request is transmitted to the data editing device 1 of the user, and a request for transfer of ownership is made (S405). Specifically, for example, the processing is performed as follows. The interactive process of the data editing device 1b is performed when the local user performs an operation on the data screen 28 or the operation screen 29 to request the remote user of the data editing device 1a to transfer ownership of an object for which ownership is set. , (“Object information”, “property transfer request”, “user name of data editing device 1a”) are output to the relay process. The relay process of the data editing device 1b transmits (“object information”, “request for ownership transfer”, “user name of the data editing device 1b”) to the data editing device 1a.
[0045]
When the transfer of ownership is requested by the remote user, the data editing device 1 displays the request for transfer of ownership to the local user by displaying, sounding, or the like (S410). Specifically, for example, the processing is performed as follows. When the relay process of the data editing device 1a receives (“object information”, “request for ownership transfer”, “user name of the data editing device 1b”) from the data editing device 1b, it outputs the information to the interactive process. I do. The interactive process changes the “owning:“ user name of the data editing device 1a ”” displayed for the object on the data screen 28 or the operation screen 29 into the “ownership request:“ user name of the data editing device 1b ””. Change to
[0046]
When the local user requested to transfer the ownership from the remote user performs an operation of granting the transfer of the ownership, the data editing apparatus 1 notifies the requesting remote user that the permission has been granted by the local user (S415). Specifically, for example, the processing is performed as follows. The interactive process of the data editing apparatus 1a relays (“object information”, “ownership transfer permission”) when the local user clicks “YES” on the permission screen 281 or 291 and performs an operation to grant ownership. Output to process. The relay process of the data editing device 1a transmits ("object information", "ownership permission") to the data editing device 1b.
[0047]
When notified by the remote user that the transfer of ownership has been permitted, the data editing device 1 of the billing source user sets the owner to the local user for the local attribute data 32 of the object for which the transfer of ownership has been requested. This allows the local user to process the object, notifies all the remote users that the ownership has been set to the local user, and updates the attribute data 32 in the data editing apparatus 1 of all the users synchronously. (S420). Specifically, for example, the processing is performed as follows. When the relay process of the data editing device 1b receives (“object information”, “ownership permission”) from the data editing device 1a, it uses (“object information”, “user name of the data editing device 1b”) as an argument. The attribute update process is called, and (“object information”, “ownership update”, “user name of data editing apparatus 1b”) is transmitted to data editing apparatuses 1 of all remote users. In all data editing apparatuses 1, the attribute update process sets the owner of the attribute data 32 of the object specified by the object information to the user name of the data editing apparatus 1b. In the data editing device 1 of all users, the interactive process displays the display of “owning:“ user name of data editing device 1a ”” for the object based on the attribute data as “owning:” user name of data editing device 1b. To "".

Therefore, according to the data editing apparatus 1 of the present embodiment, the files 30 shared by each other can be efficiently processed while synchronizing the contents among a plurality of users.

According to the data editing apparatus 1 of the present embodiment, information indicating who owns the object, whether the object is edited and not updated synchronously, etc. is displayed, and the user is guided by sound or the like. Non-owning users of an object may know that an object will be changed by future synchronous updates, allowing for smooth collaboration by multiple users.
[0051]
Further, according to the data editing device 1 of the present embodiment, the setting of the ownership and the synchronous update can be requested and permitted in two stages. That is, instead of unconditionally permitting a synchronous update for a process performed on an object performed by a user whose ownership has been granted, all users execute the synchronous update only after permitting the synchronous update. For this reason, unified processing of all users who process the file 30 can be performed.
[0052]
Further, according to the data editing apparatus 1 of the present embodiment, ownership can be set for each of the first type object and the second type object. Specifically, for example, while the user of the data editing apparatus 1a owns and processes a part of the MIDI data, the user of the data editing apparatus 1b adjusts the reproduction volume of the MIDI data for the same MIDI data. It enables collaborative work in which work is finely divided.
[0053]
Although the exclusive control device is applied to the data editing device 1 in the present embodiment, the exclusive control device may be applied to an electronic musical instrument capable of inputting / outputting, processing, and playing MIDI data, for example. Such electronic musical instruments generally include a display device for displaying and processing data, a keyboard, a volume knob for adjusting the volume of each track, and the like. .
[0054]
Further, in the present embodiment, when a processing operation is performed on the data screen 28 and the operation screen 29 by a user who does not have the ownership of the object, exclusive control is performed because the interactive process does not accept the processing operation. However, apparently, exclusive control may be performed by accepting a processing operation and not accepting a synchronous update operation. Not accepting a synchronous update operation means that, for example, when a portion displaying a processed object is clicked, “update” in the displayed menu cannot be selected. As a result, the user can freely process the object having no ownership while maintaining the consistency of the file 30.
[0055]
Further, in the present embodiment, an example has been described in which the plurality of data editing apparatuses 1 autonomously set the ownership of the object, but the data editing apparatus 1 storing the file 30 on the hard disk 14 sets the ownership. The data editing apparatus 1 may be managed in a centralized manner, and the other data editing apparatuses 1 may transmit and receive information regarding ownership only to the data editing apparatus 1 storing the file 30.
[0056]
In the present embodiment, sound source data such as MIDI data has been described as an example of data to be processed. However, data to be processed may be data created by a word processor. In this case, the data screen 28 is equivalent to a text input area of a word processor, and the operation screen 29 is a menu for displaying selection items for selecting an operation such as format setting or printing to be displayed, or instructing format setting or printing. And the like.
