  • A query expresses in a high-level language like SQL must first be scanned, parsed, and validated. • Once the above steps are completed, an internal representation of the query is created. Typically this is either a tree or graph structure, called a query tree or query graph. • Using the query tree or query graph the RDBMS must devise an execution strategy for retrieving the results from the internal files. • For all but the most simple queries, several different execution strategies are possible. The process of choosing a suitable execution strategy is called query optimization....
