2. Electronic commerce is known as E-Commerce in short.
The term e-commerce is used for describing a variety of
market transactions, enabled by information technology
and conducted over the electronic network.

3. EDI is the electronic interchange of business information
using a standardized format; a process which allows one
company to send information to another company
electronically rather than paper.

4. However, the real power of the EDI is that it
standardizes the information communicated in
business documents, which makes possible a
“paperless” exchange.

5.  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

6.  It was not until the 1970’s, when work began for
national EDI standards.
 Both client and vendors input their requirements to
create a set of standard data formats that
 were hardware independent;
 were unambiguous and could be used by all trading
partners;
 reduced labor-intensive tasks such as data-entry;
 allowed the sender of data to control the exchange
including receipt confirmation of by the other party

8. EDI transactions can be passed from many
types of computers (i.e. PC, Mac, UNIX, and
mainframe). Trading partners do not need to
use the same type of equipment. EDI messages
are hardware independent, due in part to the
X12 standard. The transactions are sent via
dedicated links, ISDN or phone lines.

9.  Translation software takes raw data and
arranges it into the X12 format or the United
Nations EDIFACT standard on the sender's
end.
 Mapping software is used to exchange
information between the company's EDI
transactions and its other internal applications
such as inventory, accounts receivable, and
accounting and ordering.

interchange, Web services and transaction delivery by

11.  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

12. ANSI ASC X12
 EDI standard in North America is the ANSI ASC
X12 standard. The X12 committee is charged with
developing "standards to facilitate electronic
interchange relating to order placement and
processing, shipment and receiving information,
invoicing, payment, and cash application data

13. UN/EDIFACT
 the ANSI X12 standards and the European
standards, known as "Guidelines for Trade Data
Interchange" (GTDI). Immediately prior to the
formulation of EDIFACT, European EDI standards
had undergone a process of reconstruction by the
United Nations Economic Commission for Europe
(UNECE)

• Cost savings
• Acknowledgements from receiving institution
• Speed
• Easy partner exchange each term
• Automated transfer articulation
• Small file size
• Lower operating costs
-Saves time and money.
• Less Errors = More Accuracy
-No data entry, so less human error.

15. • Server issues
• All technological systems need upgrades
• Staff training
• Interface with your student software system
• Move from SSN to generated ID
• Web transcript requests.
• High Dependence on the participation of trading
partners
