A filtering class structure between platform according to a plurality of protocols different from each other and an RFID middleware system performs the access of the platform according to the plurality of protocols different from each other and processes data with large capacity in real time. A plurality of discrete protocol classes manage a filter by using each protocol. The filter information about each filter is recorded in the FilterSet class. The FilterMgr class has the API (Application Program Interface) for the computation request about the filter information. When each discrete protocol class is connected to the FilterSet class through the API (Application Program Interface) of the FilterMgr class at the same time, the FlterServer class sets up the predetermined critical region and controls the access.
