Automatic query rewrite using materialized views in operations optimization in databases
Krzysztof Czajkowski, Marek Banach · 2011
The article discusses the operation of automatic query rewriting and its application in the optimization of the commands in the database. Solutions of this type allow you to significantly shorten the execution time of complex queries in complex systems, data warehouses and analytical environments. The article discusses the issues of additional mechanisms helpful in assisting the tuning process of rewriting queries, including analysis of views and queries, as well as statistics. Experiments were performed in selected database environments and their results are presented in the article.
