That is, in each document, there is no priority in the same way as the original text side and the copy side, a change processing can be executed by the same operating method to the document element on an equal position, and also, the actual condition of each shared document element is one, therefore, it does not occur that the contents of a concrete document element are different between each document.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data sharing processing system and a data processing apparatus for the same, and more particularly to a system suitable for using data having the same content among a plurality of documents displayed in multiple windows. It is a thing.

[0002]

2. Description of the Related Art For example, while a certain document (document) is being created, another document is read out using a multi-window, and the necessary data (document element) held by the other document is used as an original document and copied. May be embedded in the document being processed. Since the data contents of the original and the copy are the same, the document can be created quickly and efficiently without making an input error.

[0003]

By the way, after incorporating predetermined data into a document by the above-mentioned copying, the copied data may be changed if necessary, or the contents of the original side may be changed after the change. is there. However, in the above-described conventional document, since both documents are independent from each other, the change in one document cannot be reflected in the other document. That is, although the contents of both are the same at the time of copying, it is not possible to guarantee the identity of both data after that, and if one is changed, the data of other documents using that data must also be changed. The processing is complicated.

The present invention has been made in view of the above background, and an object of the present invention is that when a certain data is shared, each shared document can mutually process the data such as correction. The object of the present invention is to provide a data sharing processing system and a data processing apparatus capable of always reflecting data of the same content by reflecting the contents of modification such as correction on other documents.

[0005]

In order to achieve the above-mentioned object, in the present invention, the same data is shared among a plurality of documents, and the data is processed such that the data is mutually changed between the documents. A system capable of performing the following, separating each of the documents from the data,
Each document has relational information with data, and predetermined data is arranged at a predetermined position on the document based on the relational information, and each document is subjected to predetermined processing such as modification of mutually shared data. I was able to do it.

[0006]

The number of data shared by a plurality of documents is one, and each document is connected to the data based on the relational information about the document. That is, a document is constructed by arranging predetermined data on a document at a predetermined position using the relationship information. Then, when the data is modified, other shared documents also refer to the same data, so that the content is immediately modified and the identity is always guaranteed. Further, since each document is linked to one data in parallel, there is no concept of an original or a copy, and the documents are equal to each other, so that the operation content of the process is not different.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a data sharing processing system and a data processing apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. 1A and 1B show a conceptual system configuration according to an embodiment of the present invention.
As shown in the figure, it is assumed that a document has document elements (data) of "circle" and "triangle" displayed / arranged at predetermined positions as shown in FIG. It shows a case in which each of the document elements is shared by a plurality of different (two in this example) documents displayed by the multi-window system.

In the present invention, the document element is separated from each document and the shared document processing system stores and holds the relation information (document) R between the document elements. Based on the relationship information R, the shared document is linked to one document element, and based on the relationship information R, the processing system of each document being processed changes or deletes the document element. It can be processed. In this example, each document has no priority like the original side and the copy side, and it is possible to process the document elements on the same standpoint by the same operation method. Since there is only one actual situation, the contents of concrete document elements do not differ between documents.

In this example, each document element such as "circle" or "triangle" is composed of an object, and one document is constructed by a combination (link) of such objects. Further, the relation information is also composed of objects, and the contents (data structure) of the document are as follows: Information (relative relationships) such as coordinate conversion of document elements and scaling is stored hierarchically.

Next, a specific configuration of the document processing apparatus for processing each document (element) will be described. As shown in FIG. 2, first, a keyboard,
Using the input device 1a such as a mouse and / or the wireless device 1b, an event is input to the next process determining unit 4 in the document processing device 3 via the input interface 2. The type of this event input is, for example, "erase a certain document element (currently being processed)", "change a certain document element like XX", or the like.

The output of the next process determining unit 4 is connected to the document element changing unit 5 and the document element deleting unit 6 in the next stage, and based on the command data given to the next process determining unit 4. , A predetermined control signal is sent to a desired processing unit 5, 6.

Further, in this example, the above-mentioned relationship information consisting of a pointer to each document element stored in the document element database 7, a pointer to a document using the document element, and their relative relationship is managed. The relation information database 8 is provided, and the processing units 5 and 6 access the relation information database 8 to detect the address where the document element to be processed is stored, and access the predetermined address. By doing so, it is possible to execute the processing on the document element or change / delete the data of the relative relationship stored in the relationship information database 8. Note that this relational information database 8 creates a table in which pointers (addresses) and names of document elements and the like are paired, and stores the table, and is configured by objects as described above. -Of course, it may be mounted by hardware such as RAM. In the present example, the document element database 7 and the relation information database 8 are described and described separately for the sake of convenience, but in the implementation, they are stored in a mixed state in one object database.

Then, the display control unit 9 reads predetermined data from the document element database 7 based on the relationship information of the document elements related to the predetermined document stored in the relationship information database 8 and each data (object). In a state of being coupled with each other, output / display is performed on the display device 11 or the like via the output interface 10. Although not shown, an ordinary multi-window system is installed and the input device 1a
In accordance with commands from the etc., the screen of the display device 11 is divided, a plurality of documents are displayed, and by appropriately switching, various processing such as addition / change of data to each displayed document can be performed.

Next, as shown in the flow chart of FIG. 3, the function of the document element changing section 5 is to judge the change contents when a change target and contents are given.
Change of document element itself (change of shape, size, etc.)
Or whether the relative relationship is changed (position change, etc.) (S
101, 102). When it is determined that the element itself is changed, the relational information database 8 is accessed to search the address of the document element to be processed, and the data stored in the document element database 7 is changed (S103, 104).

On the other hand, when it is determined in the above step 102 that the relative relationship is changed, the relationship information (object) regarding the document element in the relationship information database 8 is specified from the information to be changed, and the relative relationship is determined. Change the data.

On the other hand, as shown in the flow chart of FIG. 4, the function of the document element erasing section 6 is such that, when an erasing target is given, first, the related information database 8 is accessed to specify the erasing target document element. It is determined whether or not it is referenced by another (S201, 202).
If it is determined that the document element is not referenced, the relational information database 8 is accessed to search the address of the document element to be processed, and the document element stored in the document element database 7 is deleted (S20).
3,204). Then, the relationship information to be deleted, which is related to the document being processed and is stored in the relationship information database 8, is deleted (S205). On the other hand, the above step 202
Referred to by others (shared)
In this case, the process jumps to step 205 to delete only the relation information held by itself (the document being processed).

In the above-described embodiment, the explanation has been made on the premise that the data sharing relationship is established in advance. However, although not specifically shown, for example, a new document element is added (created). Or by creating new sharing relationships for existing document elements,
It also has the function of building a shared relationship. For the former, a new document element is created and stored in the document element database 7, and predetermined relationship information (object) such as the stored pointer is created and stored in the relationship information database 8. This can be handled by implementing a document element creation unit that has the function of storing. In the latter case,
A pointer to a desired element (which is not currently shared (referenced)) stored in the document element database, or an access method to a document managing the element is stored data such as the relational information database 8 from the stored data. A document element adding unit that has a function of reading data for the element data and linking to the document to be processed (may also be used as the creating unit)
Can be implemented.

With such a configuration, for example, FIG.
As shown in FIG. 6, when the document B is being created, the document element C relating to the “human shape” of the other document A that has already been created can be used for the document B being created (see FIG. 8E). ). In this case, in the data structure in the relationship information management unit on the document B side, related relationship information is stored in a list structure as shown in FIG. In addition, "R" in the figure
The object indicated by is an object containing the above-mentioned relation information.

[0019]

As described above, in the data sharing processing system and the data processing apparatus according to the present invention, the shared data is made independent, and each sharing side is connected in parallel to the data. , In the processing system for each shared document, one data can be mutually modified, and other documents providing it can read the modified data thereafter. Data with the same content is always guaranteed.
