摘要

射频识别(RFID)技术在工业上是条形码的极好替代品。然而，在响应不同类型查询的背景下，大量RFID数据的管理以及数据之间复杂的关系，传统数据库并不能很好地支持。因此，本文提出了(1)基于事件的数据管理模型和(2)响应事件查询的算法。我们的方法是基于EPC信息服务(EPCIS)的规范，以满足RFID社区的总体数据需求。具体而言，在关系数据库的基础上建立面向对象模型，使所提出的组合数据模型具有高度的灵活性和语义的全面性。基于该数据模型，预定义事件查询的不同参数中隐含的各种复杂谓词被解释为对数据库的单个请求。

Event Query Processing in EPC Information Services

Radio frequency identification (RFID) technology is an excellent substitute for barcodes in industry. However, the management of a large amount of RFID data, together with complicated relationships between data, in the context of responding to different kinds of queries is not well supported by traditional databases. Therefore, (1) an event-based model for managing data and (2) an algorithm for responding to event queries are proposed for RFID repositories in this paper. Our approach is based on the specification of the EPC information services (EPCIS) to meet the overall data requirements of the RFID community. Specifically, the object-oriented model is built on the top of relational databases so as to make the proposed combined data model highly flexible and semantic comprehensive. Based on this data model, various complicated predicates implied in different parameters of the predefined event query are interpreted into one single request to the database.
