Abstract

We present a new approach to implement an object bitemporal database where both valid-time and transaction-time are represented. It is based on the DataBase Version model, which allows an effcient management of object versions. This facilitates the manipulation of past events and allows a straightforward representation of branching evolution in valid-time.
