Construct Distributed RFID Data Warehouse Based On Concept Hierarchy

Radio frequency identification (RFID) applications play an important role in business activities nowadays. With the rapidly increasing volume of RFID data, the traditional centralized data warehouses (CDW) can not process RFID efficiently. To solve the problem, this paper proposes a novel model of RFID distributed data warehouse based on concept hierarchy (RFID-CFIDDW). The main contributions include: 1) proposing a new warehousing model, 2) introducing the implementation of the new model, 3) demonstrating the utility and feasibility of the new model via experiments.
