◆ The computer-to-computer transfer of business information between two
businesses that uses a standard format
◆ In the 1950s, companies began to use computers to store and process internal data and information
◆ By the 1960s, companies began exchanging
Trang 9Electronic Data Interchange
◆ Eventually, trading partners transferred data over telephone lines instead of shipping
punched cards or tapes to each other
◆ In 1968, the Transportation Data Coordination Committee was formed, charged with exploring ways to reduce the paperwork burden
◆ Since 1918, the American National Standards Institute (ANSI) became the coordinating body for standards in the United States
Trang 10Electronic Data Interchange
◆ In 1979, ANSI charted the Accredited Standards Committee X12 (ASC X12) to develop EDI standards
◆ The current ASC X12 standard includes specifications for several hundred transaction sets (the names of the formats for specific
business data interchanges)

process in several ways, each using one of two basic approaches

Trang 21Direct Connection EDI vs Indirect Connection EDI
through a VAN Figure 9-7
Trang 22Advantages of Using a Value Added Network
◆ Users support only one communications protocol
◆ The VAN records activity in an audit log, providing an independent record of
transactions
◆ The VAN can provide translation between different transaction sets
Trang 23Disadvantages of Using a
Value Added Network
◆ Most VANs require an enrollment fee, a monthly maintenance fee, and a transaction fee
◆ VANs can be cumbersome and expensive for companies with trading partners using
different VANs
◆ Inter-VAN transfers do not always provide a clear audit trail
Trang 24EDI on the Internet
◆ Viewed as a replacement for expensive leased lines and dial-up connections
◆ Small companies can get back in the game of selling to large customers the demanded EDI capabilities of their
suppliers

transaction sets
Trang 27◆ Companies may opt to establish an indirect connection through a VAN for
Financial EDI
Trang 28Hybrid EDI Solutions
◆ Utilize the Internet for only part of an EDI transaction, ones where the
transactions are not considered a negotiable instrument
