The core components of e-business are information, communication, and transaction. Business partners use digital networks (i.e. public or private communication networks) to conduct business processes using innovative technologies to improve efficiency. Three key areas are particularly important for e-business:
E-procurement: the electronic sourcing of products and services by companies, focused on reducing costs and effort.
Online stores: the electronic sale of products and services via appropriate platforms, such as online stores.
Online marketplaces: electronic commerce via digital networks, connecting the buyers and suppliers of products and services.
There are also two further areas of e-business:
Online communities: electronic communication network between individuals and organizations, which supports data and knowledge sharing as well as the preparation of transaction decisions.
Online companies: electronic business cooperation for connecting individual company services, resulting in a virtual business with a common transaction offer.
