Many relational database management systems (RDBMS) have a query optimizer. The job of the query optimizer is to determine the most efficient and fast plan to execute a given SQL query. Query optimizer has to consider all possible query execution plans before it can determine which plan is the optimal plan for executing the given SQL query and then compile and execute that query.
