    Abstract:

    Based on the usage frequency of the data in temporal database, the storage method with three historical segments is proposed in this paper. The object history is divided into three segments, and stored in different media with various chronons. The special data structure for segmented storage is discussed, the age transfer algorithm and the compress sampling algorithm are proposed. The performance study shows that the time and space efficiency are promoted one magnitudes.
