Data processing apparatus and data processing method

A data processing apparatus generates by a stream processing control program, for a time-series first stream data group of stream data out of a time-series stream data sequence, first vector data including elements acquired by collecting respective pieces of stream data of the time-series first stream data group; generates, by the stream processing control program, for a time-series second stream data group including, as a head, a piece of intermediate stream data of the time-series first stream data group and having the same number of pieces of data as the time-series first stream data group, second vector data including elements acquired by collecting respective pieces of stream data of the time-series second stream data group; and inputs, by the stream processing control program, the first and second vector data generated respectively to a batch program to control the batch program to carry out a batch processing.
