Abstract
A database updating application for updating through a one-way data link a remote database in accordance with a change in a reference database is disclosed, which comprises a database trigger client associated with the reference database for generating a database update message in the form of a file or a data packet corresponding to the change in the reference database and sending the database update message to a send node interconnected to a receive node by the one-way data link, and a database trigger server associated with the remote database for receiving the database update message transmitted across the one-way data link and replicating the change on the remote database in accordance with the database update message. The present invention provides database update through a one-way data link that may be implemented efficiently in real time and with a mechanism for verifying the integrity and operability of the one-way data link for the purpose of database update. In addition, the present invention provides a way to combine the functionalities of the conventional database update applications with the security afforded by the use of a one-way data link.
