Database schema design theory: Achievements and challenges,ema design aims at both faithful formalization of the application and optimization at design time. It is guided by four heuristics: Separation of Aspects, Separation of Specializations, Inferential Completeness and Unique Flavor. A theory of schema design is to investigate these heuristics and to pr

Calibration of a DBMS cost model with the software testpilot,m. Despite the large body of research on optimization rules and cost approximation, little effort has been invested in the design of effective techniques for their validation. In this paper we discuss a method to calibrate cost models using the Software Testpilot, a performance assessment tool. The

,’Favourite’ SQL-statements — An empirical analysis of SQL-usage in commercial applications,ractical meaning of the DML-Part of SQL language constructs. A cost-efficient method of data collection for IBM-DB2 environments is described. We also propose a simple complexity scheme for classifying SQL statements and apply it to our data. Some of our findings are compared with SQL-features used
