1. A method of integrating large volumes of updates in a database system ( 200 ), the method comprising: integrating the updates supplied by a data provider ( 220 ) into a master file repository ( 210 ) of the database system, the integrating step including the steps of: obtaining for each individual update comprised of a coherent set of data records ( 511 ) a unique modification identifier ( 513 ) from a logistic table ( 360 ) of the database system; updating the master file repository ( 515 ) with the coherent set of data records of each uniquely identified individual update; further obtaining from the logistic table a unique commit identifier ( 523 ) for each individual update that has been committed by the master file ( 521 ); loading the updates into an active image repository ( 230 ) of the database system, the loading step including the steps of: retrieving ( 533 ) from the master file repository the coherent set of data records of each uniquely identified individual update; synchronizing the active image repository ( 535 ) by successively propagating into the active image, in the order specified by the commit identifier, each individual update, completing the propagation of each individual update into the active image repository when the loading of each corresponding set of data records is committed by the active image ( 537 ); thereby, allowing end-users ( 240 ) of the database system to start querying immediately the propagated updates from the active image repository ( 325 ).
