【Abstract】 Based on the conventional 2PL protocol, we propose our concurrency control theory for data warehouse multiple view to ensure the data consistency of data warehouse. In case different materialized views are derived from the same data source, multiple view consistency may be damaged . We present a simple and scalable algorithm for achieving multiple view consistency.更多还原
