The types of EDI were constructed based on how EDI
communication connections and the conversion were organized. Thus based on the
medium used for transmitting EDI documents the following are the major EDI
● Direct EDI
● EDI via VAN
● EDI via FTP/VPN, SFTP, FTPS
● Web EDI
● Mobile EDI
also called as Point-to-Point EDI. It establishes a direct connection between
various business stakeholders and partners individually. This type of EDI suits
to larger businesses with a lot of day to day business transactions.
EDI via VAN (Value Added Network) is where EDI
documents are transferred with the support of third party network service
providers. Many businesses prefer this network model to protect them from the
updating ongoing complexities of network technologies. See Figure 18.2
A value-added network
is a company, that is based on its own network, offering EDI services toother v
businesses. A value-added network acts as an intermediary between trading
partners. The principle operations of value-added networks are the allocation
of access rights and providing high data security.
When protocols like FTP/VPN, SFTP and FTPS are used
for exchange of EDI based documents through the Internet or Intranet it is
called as EDI via FTP/VPN, SFTP, FTPS.
Web based EDI conducts EDI using an web browser via
the Internet. Here the businesses are allowed to use any browser to transfer
data to their business partners. Web based EDI is easy and convenient for small
and medium organizations.
When smartphones or other such handheld devices are
used to transfer EDI documents it is called as mobile EDI. Mobile EDI applications
considerably increase the speed of EDI transactions.
