Automated physical design tuning for database systems has recently become an active area of research and development. Existing tuning tools explore the space of feasible solutions...
Magic sets rewriting is a well-known optimization heuristic for complex decision-support queries. There can be many variants of this rewriting even for a single query, which diffe...
