Method of integrating in real time large volumes of updates in a database

摘要

A method of integrating large volumes of updates in a database system. Each individual update includes of a coherent set of data records supplied by a data provider. The database system includes a master file repository and an active image repository. The method includes first obtaining for each individual update a unique modification identifier from a logistic table of the database system. The master file repository is then updated with the coherent set of data records of each uniquely identified individual update. A unique commit identifier is further obtained from the logistic table for each individual update that has been committed by the master file. The active image repository is synchronized by successively loading into the active image each individual update. Completion of the propagation of each individual update into the active image repository is achieved when the loading of each corresponding set of data records is committed by the active image.
