A cooperative processing system includes a first data processing component, existing on a first computer, that generates an output containing object having a function of outputting data contained therein to a stream, a pipeline section that causes the output containing object to output the data contained in the output containing object to a stream addressed to a second computer, and causes the second computer to generate an input containing object that receives the stream and stores data transferred through the stream, and a second data processing component, existing on the second computer, that receives the input containing object to perform a data process.
