    • Query optimization is a hard combinatorial optimization problem, which makes enumerative optimization strategies unacceptable as the query size grows. In order to cope with complex large join queries, combinatorial optimization algorithms, such as Simulating Annealing and Iterative Improvement were proposed as alternatives to traditional enumerative algorithms...

    • Query optimization is an integral part of relational database management systems. One important task in query optimization is selectivity estimation...

    Yossi Matiaset al. Wavelet-Based Histograms for Selectivity Estimation

    • Query optimization is an important functionality of modern database systems and often based on estimating the selectivity of queries before actually executing them. Well-known techniques for estimating the result set size of a query are sampling and histogram-based solutions. Sampling-based approaches heavily depend on the size of the drawn sample which causes a trade-off between the quality of the estimation and the time in which the estimation can be executed for large data sets...

    Christian Böhmet al. Selectivity Estimation of High Dimensional Window Queries via Clusteri...

    • The query optimizer is an important system component of a relational database management system (DBMS). It is the responsibility of this component to translate the user-submitted query usually written in a non-procedural language into an efficient query evaluation plan (QEP) which is then executed against the database. The research literature describes a wide variety of optimization strategies for different query languages and implementation environments...
