Answer / Saurabh Gangwar
An Explain Plan is a tree-structured diagram showing the steps Oracle takes to execute a SQL statement. It helps analyze the performance of SQL queries by providing detailed information about join order, access paths, filtering operations, and data retrieval strategies. By examining the explain plan, developers can optimize their queries by adjusting join orders, adding or removing indexes, and fine-tuning filter conditions.
