<p>A network data transmission system where a server (4(5)) and terminals (client computers) (1(2, 3)) sharing the server (4(5)) are interconnected through a network circuit (6), wherein each time a terminal collects data, packet creating means (223) incorporated in the terminal issues a packet command complying with DB command transmission protocols independent of the network circuit, and packet converting means (423) that the server receiving the packet command has converts the packet command to a desired DB operation command and executes it, thus allowing the DB to reflect the contents and responding the request from the terminal in real time. By mounting only a communication driver realizing TCP-IP, the terminal can operate the database server, and an effective sale managing system such as a POS can be structured using this.</p> |
