INTRODUCTION:-
Traditional electronic data interchange (EDI) has been evolving for approximately 25 years and has truly become the paperless environment.
EDI is a complicated mixture of three disciplines: business, data processing, and data communications.
Since EDI is commonly defined as the direct computer-to-computer exchange of standard business forms, it clearly requires a business process.
data processing is clearly necessary for application processing.
Data communication is then necessary for the exchange to take place.
ORIGIN OF EDI
Industry groups began a cooperative effort to develop EDI standards in 1960s.
It was firstly used in the transport industry around 1960s in the US.
It was used by ocean, motor, air, and rail carriers.
About fifty thousand private-sector companies in the United States are currently using EDI. Companies such as Federal Express, Eastman Kodak, American Airlines, Nike, Staples, NationsBank etc.
THE EDI HOST
EDI can be implemented on a personal, mini, or mainframe computer.
PCS provide many companies with a low-cost entry into EDI. PC software is less expensive, faster to install, and often easier to use than mainframe or minicomputer packages.
However, it can be difficult to integrate PC systems with business applications that reside on other types of systems.
REGISTRATION
EDI system is registered in the Internet EDI server located at University of Texas-Austin.
The registration is free.
An E-Mail request has to be sent for registration
The confirmation from the EDI server is received with an username & its corresponding password
SECURITY
Various kinds of security methods are being currently available for the EDI such as :
SFTP (Secure File Transfer Protocol)
PGP (Pretty Good Privacy)
RSA (Rivest-Shamir-Adleman) Security
Crypto Heaven
CONCLUSION
EDI is well established as effective technology got reducing costs and increasing efficiency.
EDI technologies are approximately the same age as Internet technologies.
In the past, the technologies have been mutually exclusive, but this is rapidly changing.
