Quizplus · Accepted Answer

A transaction is a series of actions that are treated as a single unit of work, such that either all actions are completed successfully or none of them can be completed. This ensures the integrity and consistency of the database. Checkpoints are periodic points at which the system records the state of the database on disk, logs are records of transactions and system events, and locks are mechanisms used to manage concurrent access to the database.
