e-Commerce

e-Commerce, electronic commerce or online sales, means the exchange of goods, services and information between computer networks, including the Internet.

Electronic commerce is not limited only to Internet. In the context of inter-firm trade for many years are used networks. Electronic transactions also carry on mobile phone networks, where we’re talking about m-commerce (mobile commerce).

In a context of strong environmental constraints, the development of distance selling tends to transform the problems of logistics.

It can be distinguished different types of relationships in e-commerce:
