ABSTRACT:
The present invention relates to a latest managing system of terminal database DB. The present invention curtails the waiting time for using a map at a terminal by deleting undefined map data from the map data of the terminal data base DB and transmitting defined map number and version number of the host at a predetermined time or according to an instruction from the host to update map data of the terminal data base to the latest map data provided by the host. A plurality of terminals are connected with a host through transmission lines. Map data of the map number other than those defined in the distribution defining file is deleted from the map data of the terminal data base either at the predetermined time or according to an instruction from the host. The current terminal version number of a map having the defined map number is transmitted from a terminal to the host through a transmission line and when the terminal version number is older than the host version number, the latest map data and host version number are transferred to the terminal to update the terminal map DB of the terminal to the latest version number.
