Transaction Logs

Transaction logs are detailed records kept by databases that track all changes made to the data, such as additions, updates, or deletions. They function like an activity journal, capturing every transaction to ensure data integrity and enable recovery if something goes wrong. If the database experiences a failure, these logs help restore the system to its most recent consistent state by replaying or undoing actions recorded in the logs. This process helps maintain accuracy, consistency, and reliability of the data over time.
