ABSTRACT:
The present invention provides techniques for answering a user's query to a database system. An embodiment provides a database querying method in which a first data item is obtained from a Data Base Management System (DBMS) database table in response to a query request. A second data item is obtained by referencing a DBMS updated log file, having log data associated with the first data item, for example a timestamp. The first and second data items are then integrated and returned as an integration result to the query request. In one embodiment the first and second data items are integrated in a virtual table in accordance with a predetermined business rule.
