RFID数据流管理关键技术

新一代传感器和RFID（无线射频识别）技术为人们提供了强大的感知、理解并管理世界的能力,同时RFID数据具有不确定性、冗余性、蕴含时空性、需要在线处理等特点,也为数据管理提出了许多挑战.本文回顾了RFID数据管理的研究发展现状,从数据流连续查询、物化视图推导规则、复杂事件处理等角度分析了RFID数据管理涉及到的几种关键技术,最后介绍一种数据流驱动的RFID复杂事件处理系统（GodEye Event Processor）的设计思想,将RFID事件查询设计成复杂连续查询,能够有效捕捉并处理复杂RFID事件.

Key Issues on RFID Data Streams Management

The new generation sensor and RFID technology provides powerful ability for perception, understanding and management world. While RFID data bears many peculiarities such as indetermination, redundancy and containing space-time etc., thus it poses many challenges for data processing and management. Survey on research and development of RFID management is reviewed in this paper. We analye several key issues on RFID data streams management from two or three angles, such as continuous query over data streams, complex event processing, and inferring rule for materializing view etc. Finally, an Data Streams drived system to process RFID complex event system, called GodEye Event Processor （GEEP）, is introduced, it devise RFID application logic into complex continuous query, and it can effectively capture ＆ process complex RFID events.
