  Abstract

Temporal databases support an efficient historical representation and operation for an object in the real world. Especially, temporal aggregates generate an additional information by means of computations from objects that is valid at past as well as current time. It is one of important areas to serve to users as various type of aggregates as possible so that they enhance the overall system performance and efficiency. In this paper, we not only introduce temporal aggregate tree strategy as an efficient processing technique for given temporal aggregate query, but also analyze the overall processing cost and then evaluate its performance.
