ABSTRACT:
A method and system for performing real-time database update transactions with disconnected database clients includes a disconnected client server (DCS) and disconnected client extensions (DCE). The DCS formats the database cell, its key, any associated database cells, and a timestamp and sends them to a disconnected database client by email. The timestamp indicates the last time the database cell or associated database cells was changed. The disconnected database client sends a reply email with the update of the database cell and the timestamp. Upon receipt of the reply email, the DCS compares the received timestamp to a current timestamp for the database cell. If they match, then the database cell is updated according to the received update. If they do not match, then the update is based on outdated information and is rejected. In this manner, reliable real-time update transactions are provided between a disconnected database client and the database.
