Abstract: Query processing in databases can be divided into two steps: selecting an 'optimal' evaluation strategy, and executing it. We first present elementary nested loop and relational algebra algorithms for query execution and point out some opportunities for improving their performance. A survey of optimization strategies, structured in query transformation techniques and access planning methods, follows. Finally, extensions for special-purpose query systems are briefly addressed.
