摘要：
In this paper we present a recovery mechanism for main memory database, which does not treat volatile RAM as a buffer and uses a limited size non-volatile RAM for efficient logging and archiving. It allows database recovery in parallel to the execution of normal transactions, it combines Undo and Redo into a single operation in many situations and eliminates the need for checkpointing. Under partial recovery our algorithm manages to identify and recovers only dirty data for bringing the entire database into a consistent state.
