Communication system links different independent databases and provides automatic updating of corresponding records in the databases.

摘要

A database interface (44) and associated communication program (48) are installed at each node in a communication network (27). The database interface (44) provides a translation between different record formats held in the databases (46) at each node and a standardized record format used to communicate records among the nodes. The communication program (48) provides a facility for transmitting and receiving records in standardized record format among the nodes. The communication program (48) automatically transmits records which have been modified at one node to all other nodes which contain corresponding records, thus maintaining current records at each node.
