A data-warehouse is updated with transaction data from various application databases periodically, and the transient data (the data not yet updated in the data-warehouse) from the application databases is transferred to an intermediary data storage. A report generator may consider the data in both the data-warehouse and the intermediary data storage in generating reports. Due to the use of the intermediary data storage, the reports may be generated on current data as well.
