Oracle Flashback Database allows you to restore your entire database to a previous point in time using a single command, rolling back any changes that were performed after the selected timestamp. In this video, learn how to use the FLASHBACK DATABASE TO TIMESTAMP command to revert changes that were done to your database and restore your database and its data to a previous point in time.
- [Instructor] The most famous feature of…Oracle Flashback Technologies is the ability to Flashback…an entire database to a previous point in time…using a single command, and without having to worry about…using external backup files or utilities.…Essentially, Flashback Database is like your own…personal database time machine.…Using Flashback Database, we can choose to restore our…database to a specific point in time in the past…using either a timestamp value, in Oracle SCN or…system change number value, or a log sequence number.…

Before using Flashback Database, let's verify that we…have data in our employee's table.…This is the table we have created in our previous video.…
