By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Current study results on Database Management have been published. According to news reporting originating from Walldorf, Germany, by VerticalNews editors, the research stated, "Semantic query optimization is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance."

Our news editors obtained a quote from the research, "In this paper, we report about a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the Pegasussystem, outperforms existing C&B systems an average by two orders of magnitude."

According to the news editors, the research concluded: "This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly."
