| 摘 要： | 为了获得RFID数据流中热门元素以及相关起源的信息,需要对RFID数据流进行带起源信息的冰川查询。以RFID数据流中单个数据对象的世系追踪为研究对象,分析在海量RFID数据流基础上返回极少查询结果的冰山查询执行机理,初步建立一个面向RFID数据流冰山查询的数据流世系跟踪原型模型。

| Abstract: | In order to get popular elements and the origin of the data in RFID data streams,iceberg queries of RFID data streams with data information on the origin of glaciers query must be made.RFID data lineage to track the application flow needs to know the origin of the data.This paper introduced the data streams lineage tracing techniques,combined with the method of the query RFID data stream,a lineage tracing model for iceberg queries over RFID Data Stream was proposed in this paper. |
