DATA FLOW CONTROL DEVICE AND DATA FLOW CONTROL METHOD

A dataflow control apparatus has a causal network storage unit that stores a causal network representing a causal relationship between a plurality of indices that include at least a plurality of device indices which are respectively data obtained in a plurality of devices and an objective index which is an index that an application controls or predicts, a device index selection unit that selects, based on the causal network, at least one device index having a causal relationship with the objective index of the application, from among the plurality of device indices, in a case where a data request is received from the application, and a dataflow control unit that controls the dataflow, such that data obtained in the device corresponding to the selected device index is provided to the application.
