A device system, method and computer program product for processing electronic transaction requests

摘要

The invention is primarily concerned with databases 110A/B which record inter-bank financial transactions. Message M1 from a first bank specifies some payment between banks. This is logged in the databases and triggers message M2 to a second bank. The second bank credit/debits an appropriate account and respond with acknowledgement message M3. Message M3 is also logged in the database and acknowledgement message M4 to the originating bank is issued. This transaction message history log is utilised during intermittent settlement operations to determine the amounts of money due to pass between the banks. The logs may be cleared after settlement. The claims in this application specifically relate to the databases 110 being clustered databases and their recording of the transaction messages.
