INTRODUCTION TO EDI…..• What is EDI? ▫ Electronic Data Interchange is the computer-to-computer exchange of business data and documents between companies using standard formats recognized both nationally and internationally. ▫ The information used in EDI is organized according to a specified format set by both companies participating in the data exchange.
HISTORY OF EDI…..• The general idea behind EDI was originated by a group of railroad companies in the mid-1960’s, in the United States.• Much of the early work on EDI was driven by the industry sectors for: ▫ transportation ▫ pharmaceuticals ▫ groceries ▫ automobiles ▫ banking
HISTORY OF EDI ….• At about the same time, the U.K. Department of Customs and Excise was developing its own standards for documents used in international trade, called Tradacoms. These were later extended by (UNECE)The United Economic Commission for Europe, and came to known as the GTDI(Guidelines On Trade Data Exchange), and were gradually accepted by some 2,000 British exporting organizations.
ADVANTAGES OF EDI….• Lower operating costs ▫ Saves time and money• Less Errors = More Accuracy ▫ No data entry, so less human error• Increased Productivity ▫ More efficient personnel and faster throughput.• Faster trading cycle ▫ Streamlined processes for improved trading relationships
DISADVANTAGES OF EDI…..• High Dependence on the participation of trading partners• Costly for smaller companies• Difficult to agree on standard to be used
VALUE ADDED NETWORK (VAN) A private network used by acompany primarily for routing, storing anddelivering electronic data interchange(EDI) messages. A value-added network(VAN) also provides other services such asmessage encryption, retransmission andsupport. VANs may be operated by largecompanies for efficient supply chainmanagement with their suppliers, or byindustry consortiums and telecom providers.

FEATURES OF VAN• Receives electronic messages and forwards them onto the recipient.• Low cost start-up• EDI translation and mapping services with Cyber Link
• Security exceeds industry standards to protect data throughout VAN.• Detailed billing.• Value Added Network protects against duplicate transmissions and will alert or discard duplicate transmissions as required.
Web Services• Applications that use a universal language to send data and instructions to one another, with no translation required.• Uses the Internet, so most of the connection problems are eliminated.
EDI VIA INTERNET….• Communication of EDI messages via the Internet.• EDI data is passed between trading partners using Internet protocols.• Protocols such as file transfer protocol (FTP), secure file transfer protocol (SFTP) and AS2 (applicability statement 2)
