    - Oracle Flashback Technology is a group of Oracle Database features that that let you view past states of database objects or to return database objects to a previous state without using point-in-time media recovery.

    - With flashback features, you can do the following:

    1. Perform queries that return past data
    2. Perform queries that return metadata that shows a detailed history of changes to the database
    3. Recover tables or rows to a previous point in time
    4. Automatically track and archive transactional data changes
    5. Roll back a transaction and its dependent transactions while the database remains online.
