A system and method for performing real-time conversion of data which is present in the form of messages on JMS-compliant or other messaging systems into database transactions, which can then subsequently be applied to multiple heterogeneous databases or other systems. In accordance with an embodiment, the invention provides a means by which data can be read from messages, and converted to a set of database operations that are then stored as a persistent trail file (for example, as an Oracle GoldenGate trail file). The operations, as recorded in the trail file, can then be routed via a network and applied to target systems as required. In accordance with an embodiment, the data can be read in real-time from the messaging system, and written out as quickly as it can be consumed to the persistent trail files.
