RFID技术可以应用到广泛的领域。特别是，RFID在商业领域非常有用，例如供应链管理。然而，这样的环境下的RFID数据量是巨大的。因此，需要大量时间从RFID数据中提取有价值的信息用于供应链管理。在本文中，我们提出了一种处理大量 RFID 数据以进行供应链管理的有效方法。我们首先定义查询模板来分析供应链。然后，我们提出了一种有效的路径编码方案，对产品流进行编码。然而，如果流很长，则与流相对应的路径编码方案中的数量将非常大。我们通过提供一种划分流量的方法来解决这个问题。为了有效地检索产品的时间信息，我们对 XML 区域使用编号方案。基于路径编码方案和编号方案，我们设计了一种存储方案，可以在 RDBMS 上高效处理跟踪查询和面向路径的查询。最后，我们提出了一种将查询转换为 SQL 查询的方法。实验结果表明我们的方法可以有效地处理查询。
RFID technology can be applied to a broad range of areas. In particular, RFID is very useful in the area of business, such as supply chain management. However, the amount of RFID data in such an environment is huge. Therefore, much time is needed to extract valuable information from RFID data for supply chain management. In this paper, we present an efficient method to process a massive amount of RFID data for supply chain management. We first define query templates to analyze the supply chain. We then propose an effective path encoding scheme that encodes the flows of products. However, if the flows are long, the numbers in the path encoding scheme that correspond to the flows will be very large. We solve this by providing a method that divides flows. To retrieve the time information for products efficiently, we utilize a numbering scheme for the XML area. Based on the path encoding scheme and the numbering scheme, we devise a storage scheme that can process tracking queries and path oriented queries efficiently on an RDBMS. Finally, we propose a method that translates the queries to SQL queries. Experimental results show that our approach can process the queries efficiently.
