Transmission and exchange method of supply chain data
GB/719257—2003
The basic content of supply chain management is to control the flow of information, logistics and funds. The control of information flow includes data collection, transmission and processing. The fast and accurate transmission of information is the guarantee of information flow in supply chain management. In supply chain management, there are the following main ways to transmit data: traditional EDI transmission, e-mail (F-mail) transmission, XML transmission and two-dimensional bar code transmission (paper EDI).

EDI (Electronic Data Interchange) is an effective means of information management or processing. It is an effective method for selecting information in the supply chain.
In EDI, the carrier of information is EDI message, which is the structuring and standardization of data in traditional business documents. The FDI messages involved in the supply chain mainly include participant information message, price sales record message, quotation request message, quotation message, purchase order message, purchase order reply message, delivery notice message, credit collection notice message, invoice message, remittance notice message, etc. These messages basically guarantee the demand for data exchange in normal trade business.
The transmission of FI messages is realized through the value-added network. The user sends the message to be transmitted to the EDI service center that specializes in processing information, and then the FII service center transmits the information to the user. Such a network ensures the accurate and timely transmission of FDI messages and can meet the confidentiality requirements of commercial data. B. 1.2 EII Advantages of data transmission
Because EDI messages are structured and standardized, they are very suitable for the requirements of mobile data processing. Through the implementation of EDI, information can be quickly obtained and processed, enabling enterprises to provide better services, reduce paperwork, better communication, improve productivity, and reduce costs. The implementation of EDI can also provide enterprises with substantial and strategic benefits, such as improving operations, improving relationships with customers, improving responsiveness to customers, shortening transaction processing cycles, reducing order cycles, and reducing uncertainty in the ordering period, thereby enhancing the international competitiveness of enterprises.
B. 1. 3 EDI Disadvantages of data transmission
The disadvantages of EDI are large investment and lack of openness. Since EDI messages are structured and standardized information, their specific applications are relatively complex. It is difficult for enterprises to develop translation software that connects databases with EDI messages. The cost of general translation software developed by professional companies is high, and due to the use of dedicated value-added networks, the cost of information transmission is also relatively large. Usually, only large-scale companies are capable of implementing EDI, and the huge benefits of EDI can be truly reflected. B.2 Extensible Markup Language (XML) Method
B.2.1 Overview
XMI (Extensible Markup Language) is a language released by W3C. XMI, like HTML, is also derived from SGML. It retains 80% of the functions of SVI and reduces the complexity by 20%. It has great extensibility and flexibility that HTML language lacks. It is a definition language that uses defined tags to describe the data elements in the file, thus breaking through the constraints of the fixed tag set of TML, making the content of the file richer, more complex and forming a complete information system. The XML standard is an open standard optimized for the Web. It is still under development and is still very imperfect. Its main related international standards are as follows:
Extensible Markup Language (XMI.) standard;
XMT. domain standard:
Document Object Model (DOM) standard:
Extensible Format Language (XSI.) standard;
Extensible Interface Language (XII) standard:
XMt. Pointer Language (Xpointcr) standard: GB/%19257—2003
R.2.2XMI. Advantages of data transmission
HirKAoNrKAca-
XMI. has unique advantages over traditional FDI. Its rich format language can describe different types of documents. XMI has a high security performance. The data sent to the structured document can be encrypted and easily attached with digital signatures. Another advantage of XMI is its low operating cost. Compared with the complex FII, XML is much simpler to use and has a low operating cost because it does not require the help of an Internet connection. Data transmission can be implemented through the Internet. B.2.3 Disadvantages of XML data transmission
XML is easy to use, widely used and low-cost. It can enable small and medium-sized enterprises to easily participate in e-commerce. However, the current application of XML also has certain limitations, which are first manifested in the imperfection of its international standards.Although XML is developing rapidly and the corresponding standards are being established, there are still some imperfections. I believe that when XML is more perfected, its application scale will expand rapidly. Secondly, although XML language is easy to use, its application still requires certain professional knowledge. Usually, a dedicated person is responsible for information transmission and processing, which is still difficult for relatively small companies. B.3 E-mail method
B,3.1 Overview
Using e-mail to transmit data is the simplest supply chain management data transmission method. Its operation method is also very simple. The enterprise only needs to generate ordinary e-mails with the required data (such as purchase orders, etc.) and then send it to the corresponding trading partners. We usually call it a semi-automated data transmission method. Because when using e-mail to transmit data, in addition to the automatic transmission of data, the generation of the email and the data processing after receiving it require human intervention. B,3.2 Advantages of e-mail data transmission For users who already have computer application systems, the cost of using e-mail to transmit data is almost negligible. The method of transmitting data by email is particularly suitable for small enterprises because of its simple operation and low running cost. B.3.3 Disadvantages of data transmission by email The disadvantages of email are very obvious. First, the data security is poor. The transmission of email on the Internet has certain security issues. The loss of letters also happens from time to time. Email does not have identification functions such as data signatures, and the reliability of data cannot be fully guaranteed. Another disadvantage of using email to transmit data is that it is difficult to realize automatic processing of received data, which reduces the working efficiency. Due to the latency of email sending and receiving, it is sometimes difficult to ensure that data is processed in time. B.4 Two-dimensional barcode method
B.4.1 Overview
One-dimensional barcode transmission (EII) data is a new data representation method that can be used for data transmission: With the continuous maturity and innovation of two-dimensional barcode technology, the data content that can be represented by one-dimensional barcode is also increasing. For example, the PDF41? Taking QR code and QR code as examples, the maximum data capacity they can represent is 1850 and 4296 text characters respectively, and their data capacity can fully accommodate small data files, which is the basis for the data transmission of supply chain management using two-dimensional barcodes: the specific operation of using two-dimensional barcodes to transmit data is as follows: the enterprise generates standardized information for the information to be transmitted (such as purchase orders), which can be FD messages or structured information agreed upon by trading partners, and generates two-dimensional barcode symbols for such information content. These barcode symbols are printed on traditional paper forms (such as order forms, loan invoices, etc.), and then the enterprise directly transmits them to the customer. Send these documents to relevant trading partners by post, fax, etc. After receiving these documents, trading partners only need to scan the barcode symbol on the document to input all the data content on the document into their own computers for processing. B.4.2 Advantages of data transmission in the form of three-dimensional barcodes The advantages of data transmission in the form of two-dimensional barcodes are simple implementation: it makes data input fast and accurate, avoiding errors that may occur in manual operations: it solves the bottleneck problem of data entry well. Since two-dimensional barcodes are usually the goods with the information represented, the information described and the goods can arrive at the same time, ensuring the consistency of logistics and information flow. 8.4.3 Disadvantages of data transmission in the form of two-dimensional barcodes
