Resumen
Nowadays, businesses are founded on the law of excluded middle and have to make a choice between two paths: they can either choose to evolve and keep pace with the technological trends, or to stagnate and wither just like a flower without water does, and so they become useless ? both ways can be probable in the current economic context. Together with the technological evolution of the world, a new type of business has emerged on the business market, namely electronic business. Numerous websites and companies which deal with online sales are present on the market. Whether they organise online auctions or offer access to information pages or databases in exchange for payment, electronic businesses represent a new manner of doing business, a domain which is currently expanding.
