  The Electronic Data Interchange (EDI) is the exchange of standardized
documents between computer systems for business use. The objective of this
study is to make Electronic Data Interchange secure to use and to eliminate
human intervention in the transfer of data between business partners so that
productivity and efficiency can be improved and also promote its usage between
two or more trading organizations. This paper provides an overview of EDI by
describing the traditional problems of exchanging information in business
environments and how the EDI solves those problems and gives benefits to the
company that makes use of EDI. This paper also introduces the common EDI
Standards and explains how it works, how it is used over the internet and the
security measures implemented. The system was executed on both local area
network and wide area network after a critical study of the existing EDI
methods and also implemented using VB.Net programming language. Finally, an
interactive program was developed that handles the transfer of files, with
special attention to the security of the items that are being transferred from
one computer workstation to another.
