Review: The ACID properties

A tomicity: All actions in the Xact happen, or none happen.

C onsistency: If each Xact is consistent, and the DB starts consistent, it ends up consistent.

I solation: Execution of one Xact is isolated from that of other Xacts.

D urability: If a Xact commits, its effects persist.

The Recovery Manager guarantees Atomicity & Durability.
