What is oracles last analyzed column?

In Oracle databases, the "last analyzed" column refers to the timestamp indicating when the database statistics for a particular table or index were last gathered or updated. This information is crucial for the query optimizer, as it helps determine the most efficient execution plan for SQL queries. The "last analyzed" date can be viewed using data dictionary views like USER_TAB_STATISTICS or DBA_TAB_STATISTICS. Regularly updating statistics ensures optimal performance of the database.
