本文通过分析超市环境RFID数据管理的特点,提出了在线数据处理与离线数据存储相结合的数据仓库模型,实现智能超市中的RFID数据管理。使用内存数据库管理物品的最新信息,使频繁的状态更新在内存中完成,提高了实时查询的速度。利用磁盘数据库的大容量存储历史数据,支持对离线数据的查询。
By analyzing the characteristics of RFID data generated in rfid-enabled supermarkets, we propose an online and offline data warehousing model to manage the RFID data, using Main Memory Database (MMDB) to improve the efficiency of real-time process and online query, using Disk Resident Database (DRDB) to store the historic data that supports offline query. The experimental results show that the proposed algorithm is efficient.
