基态修正时空数据模型的优化研究

摘要

Analyze seven kinds of existed data stored ways based on base state with amendment , based on this , the author proposed base-states optimized multi -base -states & multi -classes -delta file with amendment .Comparing with existed methods , this method has some advantages , such as, save storage space, higher resuming speed of historic data , little influence of the length of his-tory and lower influence of threshold of base state .%分析已有基于基态修正模型的7种数据存储方式，在此基础上提出基态存储优化的多基态多级差文件修正模型。与已有方法相比，该方法具有节省存储空间，数据检索、恢复效率高，受历史长短影响小，效率受基态阈值影响小等特点。
