Dynamic Damage Recovery for Web Databases

In the web context, there is an urgent need for a self-healing database system which has the ability to auto- matically locate and undo a set of transactions that are corrupted by malicious attacks. The metrics of survivability and availability require a database to provide continuous services during the period of recovery, which is referred to as dynamic recovery. In this paper, we present that an extended read operation from a corrupted data would cause damage spread- ing. We build a fine grained transact...
