In order to use EDI,
all the business partners of a company have to be able to use it.
This forms a supply chain.
The main problem with tradition VAN based EDI is that it is
extremely expensive to set up and run.
For example, it costs a large sum of money just to send a few
kilobytes worth of data. Thus, it is often out of reach for SMEs.
Furthermore, companies have to convince their trading
partners the benefits of VAN EDI.
Therefore, it is almost impossible for a company to convince
ALL its trading partners to convert to EDI.
Some trading partners will be paper-based, others will be
computerised and therefore there is little to gain from VAN EDI.
Today, there are many
different types of Internet EDI. The
basic idea however, is to transfer data via http or ftp, instead of
leased lines of the traditional VAN EDI.
It is possible to connect using dial-up connection, ISDN
modems or cable modems. Thus, smaller suppliers and trading partners are able to
trade via EDI. A simple
form would be trading partners using web-based forms with
translation software to send data to each other.
Additionally, there are different forms of Internet EDI, such
as the Intelligent Gateway EDI concept whereby some trading partners
can use the web, while others can use VANs.
There are also several advantages
and disadvantages in VAN and Internet EDI.
