Реферат: A method for incremental update of materialized views and a system for answering queries against relational databases, or object-oriented databases, or graph databases, are provided. The system comprises a Storage Engine subsystem, configured to store original data as well as materialized views and subviews in a dedicated subsystem, and a Diff Engine subsystem configured to translate Natural Algebra representations of a Natural Algebra view definition into derived Natural Algebra expressions. The system further comprises an Optimizer configured to translate derived Natural Algebra expressions into Incremental View Maintenance plans, and a Delta Extractor subsystem configured to extract any transactional changes to the original data or batches of the said changes in a form that can be passed as input to the Incremental View Maintenance plans in order to compute the changes to the materialized views.
