CONTROLLED PARALLEL PROPAGATION OF VIEW TABLE UPDATES IN DISTRIBUTED DATABASE SYSTEMS
摘要:
Aspects include mechanisms for design and analysis of flows of information in a database system from updates to base table records, through one or more log segments, to a plurality of view managers that respectively execute operations to update view table records. Mechanisms allow any base table record to be used by any view manager, so long as the view managers are using that base table record to update different view table records. Mechanisms also allow any number of view table records to be updated by any number of view managers, based on respective base table records. Mechanisms prevent the same view record from being used as a basis for updating the same base table record by more than one view manager, thereby preventing a conflict where updated information from one base table record is used more than once for updating a single view table record.
