Electronic Commerce (EC) has been brought to prominence over recent years by the popularisation and commercialisation of the Internet. However, EC is not a new phenomenon; it has been an important part of trade for many years. In addition to the consumer-oriented commerce of the Internet, EC is practised through Electronic Markets and Electronic Data Interchange (EDI). In broad terms, these three areas cover the field of EC. Written by an academic with many years experience on the subject, this book covers all three areas. The coverage ranges from the business use and implications of EC to an outline of the technical requirements.
