Description: A rollback transaction is a mechanism used in databases to undo changes made by a previous transaction. This process is fundamental for maintaining data integrity and consistency in a database management system. When a transaction is executed, it can perform multiple operations, such as inserting, updating, or deleting records. However, if an error occurs or if the user decides they do not want to continue with the changes, the rollback transaction allows undoing all modifications made up to that point. This process is carried out using specific commands, such as ‘ROLLBACK’, which restore the database state to its condition prior to the transaction. Rollback transactions are essential in environments where data accuracy is critical, such as in financial applications or inventory management, as they ensure that data does not remain in an inconsistent state. Additionally, this mechanism helps prevent data loss and ensures that operations are carried out in a controlled and secure manner, allowing database administrators to effectively manage operations and maintain trust in the integrity of the stored information.
