A RFID Spatio-temporal Data Model Oriented Supply Chain

ABSTRACT

The supply chain which applies the RFID technology in real-time locating and tracking items not only results in saving plenty of time and space due to the RFID data, but also includes the implicit semantics. To implement efficient spatio-temporal queries, as well as locate and track the moving objects, this study develops a RFID supply chain-oriented spatio-temporal data model which defines the RFID data operations of spatio-temporal data. The space and time data manipulation methods are implemented in a relational database. Finally, these methods are operated using the experimental spatial and temporal data on RFID, with which the operating time can be analyzed to verify the validity of the data model and data manipulation.
