The present invention relates to a method for generating and editing a standard electronic document in an electronic document exchange system (hereinafter referred to as an EDI system).

At present, like social overhead capital such as roads, ports, and railways, ICT has a huge impact on all industries and is an important measure of corporate and national competitiveness. Among them, Electronic Data Interchange (EDI), which provides a new way of doing business with paperless transactions, has emerged as an essential means for companies to compete globally. In the following, the definition of EDI, introduction effect, and EDI document standard, EDI communication standard, EDI software, and EDI hardware for configuring EDI will be described to help the present invention.

Conventional faxes and e-mails transmit data electronically by expressing the data in a form that can be read by an unformatted person. However, the fax and electronic mail are not standardized forms, and thus, the receiver must re-enter necessary data into a computer for processing.

However, in the EDI system, data is generated in a standard form structured by a computer application, which is fundamentally different from the above fax and e-mail, so that it can be interpreted and processed by other computer applications, and the transaction document between the company and the company can be processed. They are exchanged electronically over a network in a structured and standardized format for computer-based processing.

For example, instead of sending and receiving paper documents such as orders, invoices, and quotations by mail or in person, the transaction document data is sent and received electronically. It is possible to be delivered automatically without.

The EDI system that connects each company's information system needs only software that can generate and interpret documents in accordance with EDI document standards and communication standards without being restricted by computer hardware, software, geolocation, time zones, and communication facilities. Anyone can send paperless electronic documents anywhere in the world, anytime, to any customer.

In other words, the scope of EDI is very wide, enabling not only vertical information flow but also horizontal information flow between industries and industries, and also international information flow between countries.

Therefore, the data is repeatedly input in the conventional document processing methods such as telephone, mail, and fax, so that the processing time is delayed, the accuracy of the data by re-input is reduced, and the time and manpower are consumed. Although inefficient and complex, the use of EDI systems can reduce costs such as inventory costs, transportation costs, and data errors, improve work efficiency, improve customer service, improve relationships with customers, and improve international competitiveness.

In order to realize such an EDI system, standards for exchanged documents must be established. Since the format of documents used by each company is different, rules for the content and structure of electronic documents are required to transmit them electronically. .

Syntax rules: Rules that govern the structure and organization of electronic documents

· Data item: the unit of data that makes up an electronic document

· Define electronic documents by combining data items according to electronic document syntax rules

Document standards evolved into corporate standards, industry standards, international standards and regional standards.

Industry Standards: TDCC (Transportation, 1986), UCS (Food), WINS (Warehouse)

National (Regional) Standards: ANSIX12 (North America, 1981), UNTDI (Europe)

International standard: UN / EDIFACT (UN, 1987)

In order to enable the international distribution of information, the United Nations (UN / ECE) has established standards for exchange documents in various fields such as trade, banking, aviation, transportation and administration as UN / EDIFACT. , Message design guidelines, data item directories, data segment directories, and message directories. These international standards (UN / EDIFACT) are document standards on global EDI that have been approved by the International Organization for Standardization (ISO) as international standards.

In addition, there is a need for a communication standard to support the exchange of electronic documents. In the past, various communication protocols existed, and the EDI telecommunications company (Third Party) solved the communication problem in the middle, but the international telecommunications advisory committee, an international telecommunication standard organization (CCITT) has established X.435 and F.435 communications standards that combine EDI and the E.400 Message Handling System (MHS) to address communications issues for transmitting electronic documents. X.435 and F.435 define protocols and services for EDI document transmission, respectively.

With the advent of X.435 based on the OSI (Open System Interconnection) seven-layer model, it is possible to reliably transmit EDI documents together with multimedia data to geopolitically distributed EDI systems regardless of customer location, computer type, or communication network. It became possible.

The software for EDI requires a subscriber system installed at the subscriber (EDI subscriber) side and a message store and relay system installed at the transmission host having a function of transmitting and temporarily storing messages transmitted between subscribers. EDI is available on any hardware platform, including telecommunications modems, single personal computers (PCs), workstations, minicomputers, mainframes, and more. EDI system construction is possible at low cost, contributing to the spread of EDI.

An example of an EDI system in accordance with the X.435 and F.435 standard pin international document standards, based on the X.400 Recommendations of the International Telegraph and Telephone Advisory Committee (CCITT), is as follows:

Once an EDI system can have various hardware (H / W) and software (S / W) configurations, depending on the application and the user's environment, the software (S / W) is basically a subscriber system and a subscriber processor. , Subsystem, message store, each subsystem can be installed in various combinations according to user's hardware (H / W), software (S / W0) environment, and each subsystem is installed hardware (H / W) Platforms may vary.

FIG. 1 is a schematic block diagram of an EDI system. Each subsystem constituting the system serves as follows.

First, the subscriber system connects to a relay host equipped with a subscriber processor, a message store (MS), and a plurality of relay systems (MTAs) through a public telephone network (PSTN) and sends a message to another subscriber. Services such as retrieving and viewing messages from other subscribers.

That is, it provides various functions for the user to create and transmit or receive an EDI message, a document form generation system, a document editing system, a document conversion system, a communication processing system responsible for transmitting / receiving an EDI message between a relay host and a subscriber system; Message store access system according to the message store access protocol (P7), and a document management system for objectizing and managing the transmission and reception documents and management information.

The subscriber processor performs a function of encoding or decoding a message transmitted in the subscriber system and the message storage period. That is, the message created and transmitted by the subscriber system is encoded according to the encoding rule (ASN. 1) and transmitted to the message store, or the message transmitted from the message store is decoded and transmitted to the subscriber system.

The message store is a system that plays a role of relaying between the subscriber processor and the relay system, and receives and stores a message transmitted to the subscriber from the relay system. In addition, the user can search for the messages stored in the message store by using the subscriber system in various ways such as searching the number of messages satisfying a specific condition, taking a specific message entirely, or searching a list of stored messages. Provides the ability to The P7 protocol (message store retrieval protocol) applies when the message is delivered to the subscriber handler and the message storage period, and the P3 protocol (submission and delivery protocol) is applied between the message store and the relay system.

The relay system transmits a message submitted from the message store through the subscriber system to another relay system or delivers the message to the message store connected to the relay system. That is, the message is stored in the message store using the P3 protocol (submission and delivery protocol) or the message is received from the message store, and the message is transmitted to another relay system using the Pl protocol (message delivery protocol). In addition, a number of relay systems can be connected to relay messages, an acknowledgment service that delivers messages using the accumulative-storage method and informs the message delivery requestor of the success or failure of the message delivery. It provides various services such as support, delivery selection function such as delayed delivery, contents conversion to various media, error diagnosis function according to message submission and delivery.

2 is a flowchart of document transmission / reception in a general EDI system. The process of generating and transmitting a document is as follows.

The sender starts and logs into the subscriber system of the personal computer (20l), enters the contents of the document in the form of the document, creates / edits the document (202), converts the document (203) and selects the send menu (204). After creating (205), the relay host is connected (206) and the document is transmitted (207).

Then, the relay host receiving the document notifies the receiving party (PC) that the connection has already been started and logged in to establish a connection (208). The receiving side calls the message (209), classifies and stores the account (210), converts the document (211) and confirms the received document (212).

Based on the basic understanding of the EDI system as described above, the prior art and the present invention will be described.

In the conventional EDI system, in order to edit compatible documents, a separate program has been created for each document and provided to users.

Therefore, when a new document standard is enacted or an EDI system is applied to a new industry, a document editing program must be written at each time. When a part of the standard for a document already distributed and used is changed, the program for generating the document is modified. The difficulty of distributing them back to the user continues, and the maximum number of iterations specified in the Recommendation for dealing with repeated parts (loops) of documents that form the main framework of the International Standard (UN / EDIFACT). Since memory is allocated and used, there is a problem that memory is wasted.

The present invention devised to solve the above problems is to implement a general-purpose editing program that can create and edit any document according to the international standard, and in particular, to efficiently process the repetitive portion of the international standard document The purpose of the present invention is to provide a method for creating and editing an electronic document in an electronic document exchange system, which has been processed to convert the structure itself to dynamically allocate necessary memory according to a user's actual use state.

In order to achieve the above object, the present invention is a method applied to a general-purpose general purpose computer, comprising: a method for determining whether a user wants to edit a new file after reading a document form file, converting it into a tree structure in a memory, and storing the file; Step 1: When the user attempts to edit a new file after performing the first step, the user stores the document content data in the document content file after processing the user request on the screen simultaneously drawing the document form and the document content data of the wooden structure. Step 2: And after performing the first step, if the user does not want to edit the new file, reads the previously created and stored document content file and saves the content in the corresponding edit field of the wood frame. Document content data is processed after user requests are processed on the screen simultaneously. Characterized in that it comprises a third step of storing the contents of the document file.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

3 is a block diagram of a personal computer to which the invention is applied, where 301 is a central processing unit, 302 is a control unit, 303 is an arithmetic unit, 304 is a main memory device, 305 is an auxiliary memory device, 306 is an input device, and 307 is Each of the joule devices is shown.

In operation, the arithmetic unit 303 and the wave control unit 302 are the centers of the computer processing, so the two are collectively referred to as the central processing unit 301, and the accompanying input unit 306, the auxiliary memory unit 305, and The output device 307 is referred to as a peripheral device, etc. The main memory device is a high speed memory device that enables data and information movement between the central processing unit 301 and the peripheral device.

The central processing unit 301 is a device for performing the overall control of the present invention. The central processing unit 301 takes out and deciphers the command of a program stored in a storage device (main storage or auxiliary storage) line by line, and performs control for execution.

The memory device (main memory device, auxiliary memory device) is a device that stores the program contents of the present invention and input / output data of the present invention, and stores the output result after the processing is completed.

The input device 306 is a device that receives a user input for driving the present invention or a user input during execution.

The output device 307 is a device that serves as a medium for outputting the results output by the present invention to the user.

4 is a flow chart for creating and editing an electronic document according to the present invention. A document format file representing an international standard document structure is input and represented as a tree structure in memory, and the information of the wood structure is used. Draw the document form on the screen, and when the user edits or inquires the data in the document form drawn on the screen, the result is reflected in the tree structure and the flow of storing the contents of the tree structure into the document content file is shown.

That is, since only the contents of the document are delivered when the file is delivered in the EDI system, the present invention manages the document separately as a document form file and a document embedded file in order to efficiently support the file. It is defined so that it can be viewed in other forms, and the repeated parts of the international standard document are represented as repeated nodes of the wood structure, even if the user actually uses more than the number of repetitions defined when the form is initially created. Efficiently supports loops in international standard documents by letting Dynamically allocate and process memory.

Looking at the sequential flow in detail, first, the document format file is read and converted into a tree structure in memory and stored (401).

Document form files support the segment and data ordering of international standard messages and the loop structure of segment groups. The data stored in the document form file is classified into three types: static data, edit data, and loop data.

The static data is information for drawing a document frame (form. Shape) and supports elements such as text, lines, rectangles, rounded rectangles, circles, and bitmaps.

The edited material includes information for outputting a data item on a screen as information for a data item corresponding to the content of a document, and a storage space for storing a value of an actual data item.

The loop data has various information for expressing the loop structure of the international standard document such as a data item name, a segment name to which the data item belongs, a compound data item name, whether a required item is present, the number of loop repetitions, coordinates, and a data type.

5 is a structural diagram of a document style file according to the present invention, which abstracts the data in which the document style file is stored.

In the drawing, in order to efficiently process the loop, the document itself is defined as one LH1 segment group that repeats itself. LH1 has 571, DE1, DE2, LH2, and DE7 as child nodes, and LH2 It has ST2, OE3, LH3, and DE6 as child nodes. Similarly, LH3 has DE4 and DE5 as child nodes.

6 is an illustration of the wood structures generated in the intermediate process according to the present invention, where the LH2 loop is repeated twice and the LH3 loop is defined three times. This is an illustration when converted to.

In this case, the reason for selecting the wooden structure when displaying the document form file in memory is to extend the document form to display on the screen and to handle the repeated loop efficiently when the user edits the data item. To make it easy dynamic structure. As a result, as shown in FIG. 6, when the loop is repeated, child nodes for each frame are created.

After reading the document form file and converting it into a tree structure in memory (401) and determining whether the user wants to edit the new file (402), if the user does not want to edit the new file, the existing stored file is saved. In order to inquire or modify, a process of reading a previously created and stored document contents file and storing the contents in a corresponding location (the corresponding edit field in the wooden structure) of the generated wooden structure is further performed (403).

In this case, the method of finding the location of the items of the document content file in the tree structure is to find out which loop node of the tree structure the item currently to be processed in the document content file belongs to, and if the loop node is repeated several times, Find the number of repeated nodes. It finds which of the child edit fields is the value in the found loop node and stores the item in the document embedded file at that location.

7 is a structural diagram of a document content file according to the present invention.

As shown in the figure, LooptagSegmentldCompldBEld is a value defined in the international standard document and serves as a key for identifying exactly what the data is. For data items in the same segment, the Looptag and Segmented values are the same for each different data item, so Looptag and Segmentld are displayed only for the first data item and ...... for the remaining data items. For example, the eighth figure.

After the user attempts to edit a new file or reads a previously created and stored document contents file and saves the contents in the corresponding location of the created wooden structure, the wooden document form and the corresponding document contents data are stored in the wooden structure. Each node of is traversed and drawn on the screen (404).

First, draw the corresponding contents from the root node of the wood structure to the screen, and draw the child nodes of the root node in order. If a child node contains a loop, draw the entire neck structure on the screen by drawing the corresponding contents of the loop on the screen and drawing the child nodes on the screen in the same way as before. At this time, the coordinate (x, y) of each node is set to (0, 0) of the left vertex of the parent loop so that the x coordinate increases to the right and the y coordinate increases downward.

The wood structure of FIG. 6 is drawn on the screen as in FIG. In Figure 6, the coordinates of Lube 1, the uppermost loop, are relative to the left vertex of the entire screen, and the coordinates of Loop 2 are relative to the left vertex of Loop 1 (i.e., the left vertex of Loop 1 is (0,0)). .

After the document form and document content data are drawn on the screen (404), the tree structure is sequentially moved from the root node according to a request such as a user inputting new content or scrolling the document on the screen. Search and process the user's request (405).

If the user modifies the contents of the edit field, the contents are stored in the corresponding position in the wooden structure. When the user scrolls all or part of the screen, the tree structure is navigated sequentially and the contents of the tree structure are redrawn at the changed position on the screen.

After user request processing (405), the tree structure is searched sequentially from the root node, and the data stored in the edit field is stored in the document embedded file in the same format as in the above figure (406), and then the tree structure is deleted before the system shuts down. All memory allocated for configuration is released (407).

As described above, the present invention efficiently processes repetitive parts of international standard documents and can be used for all EDI documents, so that the EDI system can be spread and settled more quickly throughout the industry, thereby facilitating domestic informatization. Furthermore, it has the effect of improving the national competitiveness.
