RE: Oracle Explain

This must be oracle explain plan.

The EXPLAIN PLAN statement displays execution plans chosen by the Oracle optimizer for SELECT UPDATE INSERT and DELETE statements.
It also helps you to understand the optimizer decisions (for example why the optimizer chose a nested loops join instead of a hash join) and lets you understand the performance of a query.
