Research on Bi-temporal Periodic Data Model
Gong Bing · Jisuanji gongcheng · 2006
This paper proposes a new multi-granularities bi-temporal data model PMB, based on the classical HMAP model, by introducing thedefinition of transaction period parameter delay, to process the periodic data. The proposed model can efficiently deal with the problems ofenormous record items and intersectant time points existing in the HMAP model, which will save the store space and improve the speed of searchingfor data. Theoretical analysis and experimental results show that the PMB model can make n items of the list cut short to a few items. When thevalue of n is very enormous, the advantage of this model is very prominent.
