How to manage database transactions?

Database transaction management is conducted through the following steps:

1. Start a transaction: Before performing any database operations, it is necessary to start a transaction. This can be done by using the BEGIN TRANSACTION or START TRANSACTION statement.
2. Carry out database operations: Perform database operations within a transaction, such as inserting, updating, deleting data, etc.
3. Submit transaction: If all database operations are successful, you can use the COMMIT statement to submit the transaction and update the data in the database.
4. Rollback transaction: If an error occurs during a transaction or if previous operations need to be cancelled, the ROLLBACK statement can be used to rollback the transaction and restore the data to its state before the transaction began.
5. After committing or rolling back a transaction, it is necessary to close the transaction. This can be done using either the END TRANSACTION or COMMIT statement.

By following these steps, one can effectively manage database transactions, ensuring the consistency and integrity of database operations.
