Query optimization refers to the execution of a query in earliest possible time by consuming a reasonable disk space. A query execution plan is generated before execution and the optimal operator tree is got in the search space. Research with different examples is conducted in the present work by providing up to date information and example work.

Keywords: Query optimization; Query processing; Query execution; Distributed Database.
