Zusammenfassung
This paper addresses maintenance of materialized views in a warehousing environment, where views reside on a remote database. We analyze so called Change Data Capture techniques used to capture changes (also referred to as deltas) at the source systems. We show that many existing CDC techniques do not provide complete deltas but rather incomplete (or partial) deltas. Traditional view maintenance techniques, however, require complete deltas as input. We propose a generalized technique that allows for maintaining a class of materialized views using partial deltas.
