Abstract

Nowadays, one of the fundamental challenges which exists in applying RFID technology is optimal managing of a large amount of data which are produced and gathered to exploit RFID. The notion leads to the decrease of information systems productivity and also reduces the information efficiency. Recently, some efforts have been made in order to introduce different data warehouse models for RFID to utilize information. Our research aims at introducing an improved model for RFID data warehouse in supply chain. The research has manifested a new framework for managing a large amount of RFID data. Firstly, an effective model of coding data path in supply chain is initiated and then in order to retrieve time according to coding path, a numerical model of XML environment has been used. Finally, by utilizing an index technique, RFID data is aggregated which caused a considerable reduction in the volume of data and also made a dramatic fall in the response time of queries on RFID data.
