RFID data schema based on object-packing and dual path coding

The widespread applications of RFID technology have brought new challenges to the traditional data management method, as the traditional storage schema has serious shortages in RFID data warehouse environment. More and more enterprises urgently need an effective method to make use of the massive data. In this paper, based on the nature of RFID data, especially the relationship between objects in motion, we proposed a new encoding method which is called object-packing (OP) schema and dual path coding (DPC). OP schema can significantly improve the effectiveness of data compression. DPC method not only removes the constraint that there cannot be a loop in the path, but also does not decrease the encoding efficiency of object tracking. They can be an effective solution to the problems the enterprises encounter in managing and using RFID data.
