By Zhang Baogang A, Zhu Chongguang B and Wang Runsheng C

Abstract

Abstract: “Base state with amendments ” preserve data state of sometime and increment relative to base state. It reduces redundant data, but efficiency to recover historical data has changed lower. In order to improve efficiency to recover historical data, methods are proposed to construction multi-base states or multi-classes delta-files. This paper proposed a method to construction “multi-base states and multi-classes delta-files ” synchronously. to construct base states dynamically to some extent (Cao Z.,2002). 1
