An Overview of EDI Technologies
What Does Becoming EDI-Capable Entail?

EDI, Electronic Data Interchange, is still used widely in industry, and whilst there are developments relating to the Web, Internet and XML (Extensible Markup Language), classical EDI as used by UK companies over the last 15 years is still an eCommerce option which Welsh SMEs might have to adopt. This article provides a general overview of the EDI technologies which make this form of electronic trading work.

To become EDI-capable requires a number of technology components. In simple terms you will need suitable EDI software, the ability to link to an agreed communications network, and be able to process standard electronic messages used by your trading partner. Any conscientious trading partner should offer help and advice, although this is not always the case. What has to be remembered is that taking EDI on board is not like installing a fax machine. Once you have a fax machine, anyone else with a fax capability can send you information. An EDI solution, including software, network, and the standard messages, which you use for one customer, might not meet the needs of another one.

The next three sections consider the question of the technical components of EDI in a little more detail.
