Abstract

A database interface and associated communication program are installed in each node in a communication network. The database interface provides a translation from the record format of the database and a standardized format for transmission to other nodes thus providing translation between the formats of the different databases formats as records are transmitted between the databases on different nodes. The communication program transmits records that have been translated to the standardized format to nodes which contain corresponding records maintaining current records at each node. A node having a corresponding node can assign an owner. Assigning an owner causes the record to be sent to the database that is associated with the new owner. The owner has the responsibility for acting on the record. The originator of the record is also identified.
