transaction log is a log file of all actions performed on a database. It helps keep consistency and recover from unexpected failures.
The Transaction Log is a log file that keeps an audit trail of all actions performed on a database. This allows the database system to recover from unexpected shutdowns like power failures. Usually, the system will roll back changes made by uncommitted transactions and re-apply any committed transaction that did not make it to the database. This is done to keep ensure the atomicity and durability of transactions.
The transaction log can also be used to recover accidentally changed or deleted data.
