Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a network system that aims to share information resources such as expenditures.

[Conventional technology]

Conventionally, some network systems are of a distributed processing type in which workstations capable of creating and editing document data are distributed over a local area network having a host computer. In such a network system, document data created and edited on a workstation is sent to the host computer, or resources (database) held by the host computer, such as document data, are sent to the workstation.

In this case, if the document format of the host calculation example and the document format of the workstation are exactly the same, document data can be exchanged simply by adding a communication means between them. However, if the document formats are different, it is necessary to convert the document format to match the document format of the workstation or host computer that receives the document data before sending it. For this reason, some workstations or host computers have a structure in which a document conversion device is added between the workstation and the communication means.

This allows the receiving workstation or host computer to independently edit and utilize the received document.

Note that the document data includes data corresponding to text, geometric figures, bitmap figures, and tables.

(Problem to be Solved by the Invention) By the way, in the conventional network system described above, the host computer that inputs the document data sent from the workstation inputs the text ff created by the workstation.
Document data that includes data to beautifully represent Type 11 (for example, data indicating document attributes, i.e., data indicating font, font size, etc.) and information necessary for data processing (for example, character codes, etc.) is being entered.

However, the data for beautifully representing the document format in the document data as described above includes a lot of data that is not subject to data processing by the host computer n whose purpose is data processing. Therefore, when processing document data, the host computer must perform processing such as separating data necessary for data processing from unnecessary data. Requires a lot of processing time.

Therefore, network systems have the disadvantage that the resources held by the host computer cannot be used effectively due to the long processing time required to process document data on the host computer. The drawback is that data cannot be exchanged efficiently.

The present invention solves the above-mentioned drawbacks and reduces the dedicated time of the host computer for data processing of document data, thereby making it possible to effectively utilize the resources possessed by the host computer, and also to reduce the amount of time the host computer has for document data processing. The objective is to provide a network system that can improve the efficiency of information exchange.

[Means and effects for solving the problem] The present invention provides a second means for data processing document data, and a second means for data processing predetermined document data. a first means for creating/editing document data; and a first means for creating/editing document data, and a first means for removing document data. and receives the document data transmitted from the first means, and includes data corresponding to the predetermined data specified by the specifying means (data indicating at least some attributes of the document attributes) in the document data. ) is added to the document data, the removal means removes the data (
data indicating at least some of the attributes of the document)
document converting means for removing the document data from the document data and transmitting it to the second means, the document converting means includes a document converting means that removes the document data from the document data and sends it to the second means; If data is added, the data to be excluded from the data processing is removed from the document data and sent to the second means.

FIG. 3 shows a block diagram of the data conversion device e13 in the network system according to the present invention.
The data conversion device 3 includes a selection data designation section 30 and a data selection section 31. The selection data designation section 30 has 8
A memory 32 for storing files in text format that can be collected.
In this memory 32, data corresponding to data that is not subject to data processing when the host computer 8 performs data processing is registered.

As shown in Figure 4, the above-mentioned editable text format file contains data for beautifully representing the document format, that is, font attribute data consisting of elements such as character size and character position, and alignment. , paragraph attribute data consisting of elements such as line spacing, and page attribute data consisting of elements such as page number. A True symbol and a False symbol are added to each element of the font attribute data, paragraph attribute data, and page attribute data, respectively, and one of the symbols is designated by the document editing device 1. If the True symbol is specified, each element of each attribute data of the document attribute data is
The data is registered in the above-mentioned text format file as selection data indicating data corresponding to data not subject to i1s data processing.

On the other hand, if the Fa I se symbol is specified, it is not registered in the above text format file. The sorted data registered in the text format file is sent to the data sorter 31.

On the other hand, the data sorting section 31 has an area 33a for storing an input file in which attribute data input from the document editing device 1 is registered, an area 33b for storing sorted data input from the sorted data specifying section 30, and an area 33b for storing sorted data input from the sorted data specifying section 30. The memory 34 includes an area 33bi and an area 33C for storing attribute data from which data corresponding to the stored selection data has been removed from among the attribute data stored in the storage area 33a.

Note that the data that is not subject to data processing by the host computer 8 described above is defined in advance by the host computer 8.

Next, the operation of the network system described above will be explained based on FIGS. 5 and 6.

First, when the operator sends desired document data to the host computer 8 using the statement 1a collection 1, the operator performs a predetermined operation on the keyboard 11 or the mouse 12 to process the data displayed on the display device 19. The data item corresponding to the data that is not the target of data processing defined in the host computer 8 is specified from among the data items that correspond to the data that is not the target of data processing.

For example, [font = Mincho font, size = 81, position = P1]
When sending document data having font attribute data 100 of
Among font attribute data consisting of elements such as character position, if attribute data regarding font and character size is defined, the font displayed on the display device such as font: True FalseJ, Font size: "1rUe FalSeJ, [Character position: Tru
e For a data item such as FalseJ, the keyboard 11 or mouse 12 is operated in a predetermined manner to specify 7true for the font and true for the font size. Further, the character position is set to False.

In this way, the instruction data 101 having data corresponding to the data item instructed to be either TrLIe or False is sent to the data conversion device 3. Further, document data having font attribute data 100 is also sent to the data conversion device 3.

When the data conversion device 3 receives font attribute data 100 and instruction data 101 from the document editing device 1,
The font attribute data 100 is sent to the data selection section 31, and the instruction data 101 is sent to the selection data designation section 30.

The data selection unit 31 selects the input font attribute data 100.
is stored in the area 33a of the memory 34.

Furthermore, when the data sorting unit 31 inputs the instruction data 101, the data sorting unit 31 stores data corresponding to each of the instruction data 101 for which a “True” instruction has been made, such as “font” and “font size”, into the memory 32. At the same time, the data registered in the memory 32 is sent to the data selection section 31.

The data registered in the memory 32 is used as screening data for removing data that is not subject to the data processing of host calculation example 8 from the document attribute data stored in the area 33a of the memory 34. .

The data sorting section 31 inputs data from the data sorting section 31, that is, sorted data 102, into an area 33 of the memory 34.
b as a table (step 200). Further, the data selection unit 31 specifies an input file in which attribute data corresponding to desired document data inputted from the document editing device 1 is registered (step 201), and outputs data corresponding to the specified input file. It is determined whether writing of predetermined data into the file for use is completed (step 202).

If the writing of the predetermined data to the output file is not completed in step 202, the data selection unit 31 extracts the attribute data registered in the input file specified in step 201, and also extracts the attribute data registered in the input file specified in step 201 (step 202 ), the selection data 102 developed in the area 33b of the memory 34 in step 200 is retrieved (step 204).

Further, the data sorting unit 31 determines whether data corresponding to the sorted data 102 extracted from the area 33b of the memory 34 exists in the attribute data extracted from the input file (step 205). In step 205, if data corresponding to the sorted data 102 exists in the attribute data, the data sorting unit 31 selects the data in the attribute data corresponding to the sorted data 102,
Remove from the relevant attribute data. On the other hand, if data corresponding to the sorting data 102 does not exist in the attribute data, the data in the attribute data corresponding to the sorting data 102 is written to the output file (step 206).

For example, if we focus only on the font attribute among the attribute data of document data, the selection data 102 retrieved from the area 33b of the memory 34 is the attribute data of "font" and "size of one character", and If the data extracted from the file is attribute data of "font", "font size", and "character position", the data sorting unit 31 selects each of the "font" and "font size" of the screening data 102. It is determined whether data corresponding to the attribute data of is added to the data extracted from the input file.

In this case, the data sorting unit 31 determines that the attribute data of "font" and "character size" are added to the data extracted from the input file, and the attribute data of "character position" is added to the data extracted from the input file. It is determined that it is not added to the attribute data extracted from the file. Furthermore, the data selection unit 31
Attribute data of "character position" that is determined not to be added to the attribute data extracted from the input file is included in the output file.

Note that the data selection unit 31 performs the same operations as described above regarding the font attributes regarding the paragraph attributes and page attributes of the document data.

By the way, when the data sorting unit 31 finishes the above step 206, or when there is data corresponding to the sorted data 102 among the attribute data in step 205, the data sorting unit 31 returns to the above-mentioned step 202 and executes the subsequent steps, In this step 202, when the predetermined f-event has been added to the output file, the data written in the output file is output.

The data sent from the data selection unit 31 is input to the host computer 8 via the communication server and the communication device 7, and is processed by the host computer 8.

According to the embodiment described above, even if data that is not subject to data processing by the host computer 8 that performs data processing is added to the document data created and edited by the document a east device 1, the host computer 8 , as soon as the data necessary for data processing is input.

〔Effect of the invention〕

In the present invention, when data that is excluded from data processing by the second means is added to the document data created by the first means, the sentence conversion means converts the document data into the data. Since data that is not subject to processing is removed and sent to the second means, the second means for data processing can shorten the exclusive time for processing document data, and the first means can It is possible to provide a network system that can improve the exchange efficiency of document data exchange between the first means and the second means.
