What is a recovery control system in the database?

A recovery control system in a database is a mechanism designed to ensure data integrity and consistency in the event of failures, such as system crashes or hardware malfunctions. It typically employs techniques like transaction logging, checkpointing, and rollback to restore the database to a consistent state. By tracking changes and maintaining backups, the system can recover lost data and ensure that transactions are either fully completed or fully undone. This is crucial for maintaining the reliability of database operations in multi-user environments.
