An apparatus that enables real-time processing of mobile based transactions in a three-tier database by employing pending operation/locks databases at each mirror in the three-tier database and generating a token for each proposed transaction that indicates the operations/locks needed to perform the transaction. The token is passed to each mirror database to compare with the corresponding operation/lock database. When a conflict is detected, a flag indicating such is set.

Apparatus for processing real-time mobile transactions in a three-tier distributed database system

A system and method for interfacing a portable electronic device, having a plurality of commands including a plurality of resource commands and a plurality of local commands, with a remote resource over a costed communications channel includes processing the plurality of commands on the device without communicating any of the resource commands over the channel to the remote resource while aggregating the resource commands to produce a set of resource commands; communicating the set of resource commands to the remote resource over the channel to produce a resource output responsive to the set of resource commands; communicating the resource output to the device from the remote resource; and processing the resource output on the device using the set of local commands.

Remote user substitution at ODBC/CLI level and stored procedure authorization

A method that enables real-time processing of mobile based transactions in a three-tier database by employing pending operation/locks databases at each mirror in the three-tier database and generating a token for each proposed transaction that indicates the operations/locks needed to perform the transaction. The token is passed to each mirror database to compare with the corresponding operation/lock database. When a conflict is detected, a flag indicating such is set.
