The graphic data stored in the buffer 12 is transferred.

[Problems to be solved by the invention]

Since the conventional graphic database management method performs the above-described processing, in order to transfer data from one graphic database to another graphic database, an extraction program 10 and a transfer program 11 that perform separate processing for inputting and outputting data are used.
Must be provided above the database management means 6 and the database management means 8, that is, it is necessary to create separate processing means for inputting and outputting data above the database management means. It is necessary to use the database management means properly while the higher-level processing means always recognizes whether the user is operating the database. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. Even when a plurality of graphic databases are handled, there is no need for a higher-level processing means to consider switching of the active graphic database. It is an object of the present invention to provide a graphic database management system capable of processing data transfer in the same manner as handling a single graphic database.

[Means for solving the problem]

The graphic database management method according to the present invention comprises: an identifier generating means 4 for generating a unique identifier between a plurality of graphic databases 7 and 9 from an identifier of data for each graphic database and an identifier of the graphic database; Database switching means (database switching program) for obtaining an identifier of data for each graphic database and an identifier of the graphic database according to an identifier or an instruction from the coordinate input means (coordinate input device 2) and switching the graphic database during editing work. 5) When the contents of one graphic database are transferred to the other graphic database, the contents are displayed on the display means (display device 1), and the graphic to be transferred in the contents of one graphic database is displayed. Instructed by the unique identifier or the coordinate input means, the database Switching the process from one of the graphic database to the other graphic database by the switching means,
The editing processing means (editing program 3) edits the graphic data in the other graphic database.

[Action]

For example, when transferring the contents of the graphic database to the graphic database 9, the contents are displayed on the display means (display device 1), and the graphic to be transferred in the contents of the graphic database is a unique one generated by the identifier generating means 4. It is designated by an identifier or coordinate input means (coordinate input device 2). Thereby, the database switching means (database switching program 5) switches the processing from the graphic database 7 to the graphic database 9, and the editing processing means (editing program 3) edits the graphic data in the graphic database 9.

〔Example〕

FIG. 1 is a block diagram showing a configuration of a graphic database processing apparatus using a graphic database management system according to one embodiment of the present invention. 1, components corresponding to those shown in FIG. 2 are given the same reference numerals, and descriptions thereof will be omitted. In FIG. 1, reference numeral 3 denotes a display device 1 having a multi-window display function using a coordinate input device 2 or the like.
The editing program 4 as editing processing means for editing the graphic database by designating the contents of the graphic database displayed in. Identifier generating means 5 for generating an identifier which is a unique target between the databases 7 and 9, the unique identifier or the data identifier of each graphic database and the identifier of the graphic database in accordance with an instruction from the coordinate input device 2. This is a database switching program as database switching means for switching the graphic database during the editing operation. The unique identifier is unique among a plurality of graphic databases 7, 9 passed between the editing program 3 and the database switching program 5.

Next, the operation of this embodiment will be described. First, the contents of the two graphic databases 7, 9 are displayed on the display device 1 having a multi-window display function. At this time, when the contents of one graphic database 7 are transferred to the other graphic database 9, the graphic to be transferred in the contents of the graphic database 7 is a unique identifier generated by the identifier generating means 4 or the coordinate input device 2. Indicate by Thus, the database switching program 5 edits the unique identifier obtained by adding the identifier of the graphic database (identifier of the graphic database obtained from the input window) to the identifier of the data (identifier of the designated graphic) for each graphic database. Return to The editing program 3 then calls the database switching program 5 to obtain information on where to place the contents, and obtains coordinate values indicating the location. At this time, the database switching program 5 switches the processing to the graphic database according to the contents of the input window. Thereby, when the editing program 3 outputs data, the data is given to the graphic database 9. That is, the graphic data to be transferred from the contents of one graphic database 7 is transferred to the other graphic database 9. According to the above embodiment, a plurality of graphic databases can be managed by a single graphic database identifier, and the work graphic database is switched by switching the work window from the upper level of the database management means. Thus, a special procedure for exchanging data between the graphic databases can be omitted.

In the above embodiment, the case where the graphic element instruction and the transfer device are input from another window by the coordinate input device is shown. However, when the input is performed from the same window, the graphic database switching process does not occur in the database switching program. The upper-level editing program can also perform data editing in the same graphic database by performing exactly the same processing.

〔The invention's effect〕

As described above, according to the present invention, an identifier of a graphic database is added to an identifier of data for each graphic database, an identifier to be unique among a plurality of graphic databases is generated, and the unique identifier is generated. Alternatively, according to an instruction from the coordinate input means, the identifier of the data for each individual graphic database and the identifier of the graphic database are obtained to switch the graphic database in operation. There is no need for the processing means to consider switching of the graphic database in operation, and an effect is obtained that the exchange of data between graphic databases can be processed in the same manner as handling a single graphic database. That is, according to the present invention, it is possible to perform the same processing as in the case of operating a single graphic database with a single procedure that unifies the data operations of a plurality of graphic databases, thereby improving the editing efficiency of the graphic database. The effect is obtained.
