【摘要】 为有效地存储和管理海量数据,提出了一种基于路径的射频识别技术数据立方体构建方法。该方法不受射频识别技术系统的物理分布影响,只与路径数据库的规模有关;在最小兴趣层和观察层之间,选择物化某些立方体单元,以保证能够快速构建立方体结构和较快响应系统不同用户的路径查询。理论分析和实验结果表明了该方法的有效性。更多还原

【Abstract】 To effectively store and control mass data,a path-based Radio Frequency IDentification(RFID) data cube construction method was proposed.This method depends only on the size of path database but not the distribution of the RFID system.Some cuboids between the minimal interest layer and the observation layer were chosen to materialize,which costs less time to both construct the cube and answer the path queries from different users.Analytical and experimental results show the effectiveness of this method.更多还原
