E-business means doing business on the Internet. This can include any business process - to include buying and selling, which is known as E-commerce. The arranging for transport by sea or the buying and selling of things needed for ships that sail from port to port are among the world's oldest professions. Many ship owners, operators or managers still conduct business the old-fashioned way, building and maintaining close and longstanding relationships with suppliers or customers. While the dot-com craze of a few years ago has passed, E-business is revolutionizing several important business processes in the maritime industry. Computers can aid in the design and construction of vessels, and the Internet can be used to transmit design information and changes instantaneously.
