EDI Issues

• Traditional EDI Systems
• Value Added Networks (VANs)
• Financial EDI
• EDI Systems and the Internet

EDI refers to the exchange of electronic business documents between applications

Traditional EDI Characteristics:

• Identified trading partners
• Expensive initial investments
• Dedicated leased line or utilization of a Value Added Network (VAN)
• Standard, inflexible data sharing
• US standard: ANSI’s x12
• UN standard: EDIFACT
• Batch connectivity
• Low transaction costs

• During the 1990’s, EDI use grew 30% each year
• Currently growing at 15% per year
• 1999 total EDI transaction value $3 trillion
• Estimated 2003 value $4 trillion

Value Added Networks (VANs)

• Third-party network services
• EDI translation software
• Security assurances
• Independent audit trails
• Reliable transmission (redundant systems)
• EDI systems development assistance
• Employee training
• Exact, explicit contracts with trading partners
• Authorized data sharing

• Lower processing costs
• Tighter relationships between suppliers and customers
• Lowered error rates
• Decreased lead and cycle times
• Decreased inventory shortages and problems
• Increased product differentiation
• Better information for all trading partners

Utilizing the Internet (involving Browsers and a markup language, e.g., HTML) for electronic transactions:

• Much lower initial investment costs
• More connectivity: greater sharing and tracking of data
• Allows for new partners
• More flexibility with XML (See next slide)
• Creates serious security concerns
• Risk of loss of packets or sniffed packets
• Loss of third-party audit trails and authentication
• Electronic Data Interchange – Internet Integration (EDIINT) group currently defining standards for encryption and digital certificates

Connectivity

• Many VANs providing services
• Standard is XML (Extensible Markup Language)
• Provides a universal data format
• Allows data objects to be serialized into text streams
• Is easy to parse, so it can be used to pass data between processes
• Allows for custom tags, which can be passed easily over a variety of network protocols
• Has companion standards to support browser presentation, hyperlinks, and querying

• EDI/Internet Solutions increase the demand for accountants to know
• How the audit has become more complex
• The risks surrounding Internet business processes
• Reliance on data from the Value Added Network
• Trading partners’ data integrity and system reliability
• Encryption of data
• Authentication of trading partners
• Digital Signatures and Nonrepudiation
• Firewalls
