1. Introduction
This course offers students a systematic approach to the fundamental principles of e-commerce. The course prepares e-commerce projects.

The course starts with business models of e-commerce.

The classification of commodities, e-catalogs, and harmonized transactions are identified as the backbone of e-commerce.

International standards for the classification of commodities are introduced and applied.

E-catalogs are analyzed and applied.

Harmonized transaction standards are analyzed and discussed.

Existing standards developed within e-commerce are compared with other standards like ISO standards. Concepts for the extension of e-commerce standards are developed.
