Abstract

We discuss the importance of analytic SQL statements with complex expressions in the business intelligence and knowledge discovery applications. We report the recent improvements of the execution of complex expressions in the Infobright’s RDBMS, which is based on the paradigms of columnar databases and adaptive rough computations over the granulated metadata layer.
