Evolution of Oracle Time Machine: FlashBack“It started by mistake”. We human beings tend to make mistakes. But what happens when this error is made by the database user. Is there a simple concept of trash or a simple concept of time travel? The answer is YES, there are. Sometimes it's just a simple query or some data cleaning methods used by users or data librarians. Whatever the cause, data loss is a very common phenomenon. Backup and recovery methods are provided by Oracle database management systems that ensure the safety of valuable data in the event of data loss. However, not all data loss situations can use the comprehensive and tedious recovery concepts from backup. Oracle introduced flashback features starting with Oracle 9i to address simple data recovery needs. Oracle's Time Travel Concept: Oracle FlashbackOracle has developed a suite called Flashback Technology that allows Oracle application users and database administrators to go back in time and examine their database objects and data in a simple way. previous state without having to restore using backup media. Flashback query allows a user to quickly and easily view data as it was at any given time in the past, even when it is edited and committed, whether it is a single row or the entire row. 'complete table. What situations require the use of the flashback feature? According to Oracle documentation, Flashback technologies are applicable to repair the following user errors. • DROP TABLE statements, intentional or not. unintended batch work or widespread application errors. There are more flashback features than one can imagine. All these features were piled up in the middle of a paper......the moment you turned on the FDA. This proves that Oracle Time Machine has become more advanced. In fact, this may be before the introduction of Flashback functionality in Oracle Database and even before the launch of the Oracle RDBMS product. The recovery of your database is in your hands! If you have preserved history using another mechanism, such as triggers, you can import that history into Flashback Data Archive. Conclusion: To compensate our errors of accidental data deletion and recover our required data in the shortest possible time, we can use Oracle Time Machine i.e. Flash Back technology. The FlashBack concept can play an important role in a flexible manner to restore data affected by logical corruption. Since this is a unique Oracle feature, there is plenty of documentation and support available for each step of implementation in an Oracle database
