摘　　要：Based on public switch telephone network and peer to peer communication mode, a distributed multidatabase system is presented, and the characteristics and data distributing mode of it are discussed. It adopts horizontal fraction of data and totally duplicates the data structure in all physical nodes. Data is stored in the neighborhood, so the efficiency of communication is increased.Based on public switch telephone network and peer to peer communication mode, a distributed multidatabase system is presented, and the characteristics and data distributing mode of it are discussed.
