3. Meaning
• Electronic Data Interchange (EDI) refers to the
• structured transmission of data between organizations by electronic
means.
• A way to exchange transcripts (and other important
• data) without paper.
• The National Institute of Standards and Technology in a 1996
publication defines Electronic Data Interchange as "the computer-
to-computer interchange of strictly formatted messages that
represent documents other than monetary instruments.
• EDI can be transmitted using any methodology agreed to by the
sender and recipient. This includes a variety of technologies,
including modem (asynchronous, and bisynchronous), FTP, Email,
HTTP, AS1, AS2, etc

6. Working of EDI
1. Exchange of data with several trading
partners directly in a standard format.
2. Interaction with multiple companies through
a central information clearing house.
• Here each companies add EDI program to its
computer to translate the company data into
standard formats for transmission, and for
reverse translation in the data.

7. Benefits of EDI
• Generation of a paper document on a form by software
• application.
• Delivery of a few copies of document to the internal
dept to be filed and others to the trade partners via
postal service.
• Retyping the document received by the trading partner
on the form into their computers which may offer
introduce errors.
• Generation of a paper acknowledgement and sending
it to the originating company.
• Generation of a file containing the processed
document by the application program.

8. Benefits of EDI cont…
• Conversion of the document into agreed
standard format.
• Electronic transmission of the file containing
the document over the network , which may
link the originating company and its trading
partner.
• Automatic generation of the receipt and its
delivery over the network to the originating
company.

9. Features of EDI
• Exchange of structured business information in standard
formats between computers.
• It has reduced data entry link, eliminates the need for a
paper bases system and improved business cycle.
• EDI transfer structured business documents internally
among groups of departments or externally with its
suppliers, customers and subsidiaries.
• In EDI, information transferred over a network will not have
to read, retyped or printed but must have predefine
structure agreed between the two company's which send
and receive data.
• The two companies or groups which exchanged information
through EDI are called the Trading Partners.

10. Components of EDI
• There are 3 types of component
1. Application service
2. Translation service
3. Communication service

11. File Types
• EDI creates following files as a document passes through the
system:
1. Internal format file (IFF):-
It contains single document for single trading partner.
2. External format file(EFF):-
It contains same data as the internal format file translated into the
appropriate standard document format.
3. Transmission file:-
It contains one or more document for the same trading partner.
Documents of same format are packed into an functional groups.
The functional groups going to one trading partner are packaged
into an interchanged set. An interchanged set.
An interchanged set contains one or more functional groups of
documents with the same sender and receiver.

12. EDI software
1.Translators:-
• Every EDI sender and receiver should have EDI translator.
• It varies based on the computer on which it is going to reside.
• The computer may be a micro computer or a midrange or a
mainframe. Translator reads the fixed length
• file and generates valid Edi standard and maintains control
information.
2.Application link software:-
• There are 2 components of software, which is generally used to link
the existing business application to the EDI data.
• One is the translator and the other is application link software .
Application link software is used to collect information from the
business application and then it formats into fixed length computer
file and passes it onto translators.

13. EDI services
• 1. Application Services :-
• It provides the link between application and
EDI.
• It allows you to send documents from an EDI
system.
• The set of callable routine is used to transfer
document from the business application into
EDI document destination can be either intra-
company or to the external companies .

14. 2. Translation service:-
• Converts the out going documents from an
internal format file to an agreed external
format.
• Translates internal document from external
format to EDI internal format file.

15. 3. Communication service:-
• The communication service sends and
receives transmission files to and from the
trading partners either directly or by using
party service called a valued added
network(VAN).
