Algorithm of Inverse Query on Time Series Data
-
摘要: 针对时间序列中的反向查询,提出了一种新的索引方法——ES索引,介绍了ES索引的建立、查询过程,并对数据动态更新时的ES索引作了详细的阐述,简要说明了ES索引在点、范围及近似查询中的应用。Abstract: This paper present a new method——EP-index which is used in time series data for inverse query.The procedures of establishing ES-index and querying are introduced.In addition, when data are appended, the dynamic procedure of establishing ES-index is expounded.Lastly, point interval and approximate search are introduced.
