Asynchronous incremental maintenance of multiple materialized views over shared multi-version source views
摘要
Abstract
To resolve the problem of the inferior performance of multiple materialized views maintenance through the current compensation and multi-version methods, a novel asynchronous multiple materialized view maintenance schema SMVM (source multi-version view maintenance) based on shared multi-version source view was proposed. In SMVM, materialized views in data integration site could straightway define on share-cited multi-version source views of multiple data sources, and send view maintenace query based on version to the other related data sources after received the data updates of source view for asynchronous incremental maintance of multiple materialized views. It not only avoided incremental query anomalies due to concurrent updates of data source but also improved the efficiency of asynchronous incremental maintenance of multiple materialized views. Furthermore, the compensation method of view increment utilizing the tuple-identifier made maintenance of source views more effective. Finally, experimental results demonstrated the feasibility and validity of SMVM sufficiently.关键词
