1 is an exemplary configuration diagram of an XML and non-XML based e-commerce system according to the present invention.

As shown in FIG. 1, an XML-based sales system 102, a purchasing system 103, a delivery system 104, a payment system 105, and a non-XML-based system in an e-commerce common framework 101 environment. Purchase request (111, 113, 119), invoice (112, 114, 120), shipment request (115), shipment result (116), payment request (117), payment result ( 118) shows the business of exchanging business, and the existing non-XML purchasing system interoperates with XML-based e-business systems through the XML adapter (107).

All systems, including the XML adapter 107, exchange information with each other through an XML business document broker, and the information is in the form of an XML document. The XML adapter converts the information of the non-XML based system into an XML standard document and delivers the information to the XML based system, and vice versa. Pass to the destination.

2 is a diagram illustrating an embodiment of a process of an XML adapter according to the present invention, in which a non-XML e-business system 202 to 205 uses a non-XML business document through an API (Application Program Interface) of an XML adapter. To send an XML file to an XML-based e-business system.

As shown in FIG. 2, the XML adapter 201 receives the unstructured messages 210 and 211 sent by the non-XML business systems 202-205 and then converts them into structured XML business documents using XML. And send it to an XML-based e-business system. In addition, after receiving an XML business document in the opposite direction, the message is converted into an unstructured message and transmitted to the non-XML business system 202 to 205, and the XML-based e-business system and the existing non-XML e- It serves to facilitate the exchange of information between the business system (202 ~ 205).

3 is an embodiment configuration diagram of an XML adapter according to the present invention. The XML business document is sent to an XML-based e-business system using internal components of the XML adapter and an API, and vice versa. It shows how to convert the data into internal data of a non-XML business system.

The XML adapter 310 receives unstructured messages expressing business documents and business interactions in CPU languages such as C, C ++, and Java from existing e-business systems, converts them into XML business documents, and sends them to the XML business system. And converts the XML business documents 302 and 303 sent by the XML e-business system (eg, an XML sales system) 301 into internal data of the existing e-business system.

As shown in FIG. 3, the XML adapter 310 includes a transmission type (eg, HTTP, SMTP, CORBA, etc.) designated by a sender in an XML business document, and a destination business system address (eg, a URI, an e-mail address, XML document sender / receiver 311, XML e that receives <IP address + service name, etc.) and sends XML business document to the requested business system in the requested form, and receives XML business document using HTTP, SMTP, CORBA. An XML parser 314, which parses XML e-business documents received from the business system and then builds an object source tree with each element in the XML document. An XML / non-XML message converter 312 that converts the internal data structures into an XML business system or vice versa, and a non-XML business system 321-324. Receiving a transmission request message of the XML document in a business system from, and including a conversion result value of the whole XML document from the business system, the non--XML message transmitter / receiver 313 to transmit a non--XML system.

The XML document transmit / receive unit 311 makes the application of the transfer request, parses the XML document (parsing), each element (elements) object source tree (source tree) has in the XML document after. In other words, classify the object to handle the contents of the XML document programmatically.

The XML document parser parses the XML e-business document received from the XML e-business system and then builds an object source tree with each element in the XML document. In other words, the content of an XML document is object-classed so that adapter components such as converters can handle it.

The XML / non-XML message converter 312 performs the function of converting XML business documents into an internal data structure of a non-XML business system or vice versa.

The receiver of the non-XML message transmitter / receiver 313 receives a transmission request message of the business document from the non-XML business system 321 to 324 to the XML system, and the sender converts the business documents from the XML system as a result value. Is sent to the non-XML system.

Application Programming Interfaces (APIs) provide routines and data structures for existing non-XML business systems to access and send messages to and from the XML adapter 310 to interoperate with XML-based e-business systems. .

The existing non-XML purchasing system 321 sends a purchase request to the XML-based sales system 301 through the XML adapter 310, and receives the invoice as a result value is as follows.

First, the non-XML purchasing system 321 requests a purchase based on a data structure in the API provided by the XML adapter 310 to send a purchase request to the XML-based sales system 301 via the XML adapter 310. Send a message 331. Here, the data structure includes data types, operations, and the like that the XML adapter 310 uses when creating an XML business document.

Next, the receiver of the non-XML message transmitter / receiver 313 checks the data reception signal through the socket, which is a communication channel, and receives the data through the socket when the reception signal arrives, and receives an XML / non-XML message converter. 312 converts the purchase request message 331, which is the received data, into an XML message using the DOM / SAX interface of the XML parser 314.

In addition, the XML document transmitter / receiver 311 includes a transmission type (eg, HTTP, SMTP, CORBA, etc.) designated by the sender in the XML business document and a destination business system address (URI, e-mail address, <ip address + service name). And the like, and transmit the XML business document 302 for the purchase request to the counterpart XML sales system 301 in the requested form.

The XML sales system 301 checks the name and number of items requested for purchase, checks its own product inventory database and makes a payment request to the bank based on the buyer's payment information in the purchase request, The result is a payment acknowledgment, a delivery request to the on-line delivery system, a result of the delivery, and an invoice 303 written in XML to the buyer.

The XML document transmitter / receiver 311 receives a request for transmission of the invoice 303 written in XML as a response document for a product purchase request from the XML-based sales system 301 using HTTP, SMTP, and CORBA.

The invoice 303 written in XML is parsed by the XML parser 314 and then an object source tree is created with each element in the XML document.

The XML / non-XML message converter 312 converts the invoice data in the object source tree into an internal data structure of the non-XML system 321-324.

The sender of the non-XML message sender / receiver 313 uses the URL (or e-mail address, <IP address + service name>) and transmission type information of the recipient (purchase system) 321 in the XML business document. Invoice message 332 is sent to the non-XML purchasing system 321.

Next, the non-XML purchasing system 321 adds the product count to its product inventory database after receiving the invoice.

4 is a flow diagram of an embodiment of a data transfer method between an XML based system and a non-XML based system according to the present invention.

As shown in FIG. 4, first, a message transmission channel of a non-XML document receiver and an XML document receiver is monitored (401), and a check is made (402) of whether the message is a non-XML document.

As a result of the checking, if the document is a non-XML document, the XML / non-XML message converter converts the received message into an XML message using the XML parser's DOM / SAX interface (403), and the XML document sender / receiver receives the XML business document. Identify the sender's specified transmission type and destination business system address (404).

If the address of the destination business system is correct (405), and if the address of the target business system is correct, the XML business document is transmitted to the counterpart business system with the requested transmission type (406). The process proceeds to the monitoring process 401, and if the address of the target business system is not correct, the process proceeds to the process 401 to monitor the message transmission channel.

As a result of the verification (402), if it is not a non-XML document, the received XML document is parsed using an XML parser and an object source tree is created with each element in the XML document (407).

The data in the object source tree is then converted into an entity shared with a non-XML system (408) to confirm that the address of the destination business system is correct (409).

As a result of the confirmation, if the address of the target business system is correct, the process proceeds to the step 401 of transmitting the business document to the counterpart non-XML business system (410) and monitoring the message transmission channel (401). If it is not correct proceed to step 401 to monitor the message transmission channel.

The present invention is a technology that can be used to solve the problems of interoperability between an XML-based e-business system and a non-XML-based e-business system, and provides an environment in which e-business systems around the world can interoperate. Procurement system, EDI system, Internet financial system, sales / purchasing system, catalog as a foundation technology that can be used to develop software that provides an environment for developing and operating an e-business system that can buy and sell products between markets. The use and ramifications of the invention are enormous because they provide an interoperable environment for all e-business systems via the Internet such as systems, payment systems, directory systems, online delivery systems, auction systems, and the like.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.
