Description |
A temporal database supports both real-world (i.e. valid) time and transaction time, and provides the rollback capability. A historical database, on the other hand, supports only the valid time. The paper shows that the rollback capability can be provided for the historical databases by making use of logs, and this is proposed as an efficient alternative to implement temporal databases. The proposed method is shown to be more efficient when the number of rollback queries is not high. Algorithms are presented to apply corrections to the historical databases and for the rollback operation.
