Abstract

A data distribution processing system and a data distribution processing method in the system including a data processor having a memory capable of separately storing data display formats and corresponding data and a plurality of terminals each having a memory capable of storing data display formats. The data processor beforehand stores the data display formats and delivers the display formats to one of the terminals for storage in that terminal'"'"'s memory. The data processor sends, in response to a request for data associated with the data display format from the terminal, data related to the data display format in the processor'"'"'s memory to the terminal requesting the data. The terminal sends, in response to an entered specification of a data display format, a request for data associated with that data display format to the data processor, reads the data display format from its own memory together with the data sent form the data processor in response to the request. The terminal then displays a combined image. Also in the terminal, in response to the display, data is manually inputted and is then sent to the data processor so as to be stored in the processor'"'"'s memory.
