| Abstract: |
| Radio Frequency Identification (RFID) technology has been applied to many different fields.Especially,it is very useful in the monitoring and management of the supply chain.However,in such an environment,enormous RFID path information data will be generated,from which it therefore takes a long time to extract valuable information.In this paper,the path of items in the supply chain is effectively encoded by use of the prime number encoding which is currently a widely used coding technique and can not only compress the data volume but also is convenient to retrieve path information.A storage scheme is devised to support efficient query processing on an RDBMS .Finally,a method by which query templates are converted to SQL queries is proposed. |
