There is provided a method of maintaining a hybrid OLTP and OLAP database, the method comprising: executing one or more OLTP transactions; creating a virtual memory snapshot; and executing one or more OLAP queries using the virtual memory snapshot. Preferably, the method further comprises replicating a virtual memory page on which a data object is stored in response to an update to the data object, whereby the updated data object is accessible for OLTP transactions, while the non-updated data object remains accessible for OLAP queries. Accordingly, the present invention provides a hybrid system that can handle both OLTP and OLAP simultaneously by using hardware-assisted replication mechanisms to maintain consistent snapshots of the transactional data. |
