Abstract: 
Logging and recovery ensure that failures are masked to the users of transaction-based data management systems by providing automatic treatment for different kinds of failures, such as transaction failures, system failures (crashes), media failures and disasters. The main goal is to guarantee the atomicity (A) and durability (D) properties of ACID transactions by providing undo recovery for failed transactions and redo recovery for committed transactions. Logging is the task of collecting redundant data needed for recovery.
