Electronic data exchange EDI

For security problems, people have been scientifically standardized in the initial e-commerce, which is reflected in the early EDI. EDI (Electronic Data Exchange Electronic Data Interchange) was born in the late 1960s S and developed into a standardized file exchange system for electronic commerce in 1980s. Unlike some emerging electronic data formats, it is always in the process of upgrading. On the contrary, it has always maintained its stable leading position for its wide application in international e-commerce, applicable to various e-commerce documents and data exchanges, including applicable to customs, finance, and transportation. Insurance and commodity inspection are also applicable to areas such as remote teaching, remote conference, medical care, and information consulting. In short, EDI is the de facto standard association of electronic text, text, or document data. All files sent and received through EDI are considered accurate and valid. Therefore, some professional enterprises set up EDI websites on private networks or the Internet to provide EDL Information Exchange Services for banks, enterprises, and other institutions in the society to ensure the security and reliability of E-commerce information; or develop an EDL standard file conversion system for customers and enterprises to unify business documents of different formats or texts to international ide standards.

Your trading partner retrieves emails from the mailbox online. EDI translator opens the envelope and converts the data in the envelope from the standard format to the readable format of the internal application system. For files defined in your business application system, you need to use the EDI er to generate a ing to describe the relationship between their data domains and EDI standards, the EDI translation software translates internal application files into EDI standard files accordingly.
