ABSTRACT:
A distributed data-base communication network system includes a plurality of terminal stations which respectively contain data-base devices and which are associated with one another by means of data communication lines. A data-base management apparatus is provided in each of these stations and includes an internal load monitor device for monitoring the accessing load of the internal data-base device of the internal station and an external load monitor device for monitoring the accessing loads of the data-base devices of the external terminal stations. A data-base load distribution management device is connected to the monitor devices, and automatically transfers at least part of the data-base information of the internal data-base device to a selected one of the external terminal stations when the internal data-base accessing load has exceeded the maximum permissible level, thus enhancing the uniformity of distribution of the data-base load of the communication network.
