In a work flow system in which work defined beforehand with respect to data processing is executed by a plurality of workers in a plurality of nodes connected to each other through an information network, data processed in a branch source node is divided into split data so that the split data are distributed to some branch destination nodes. The split data processed in the respective branch destination nodes are connected as input data to be given to a connecting destination node. A work flow control engine sets data start and end positions of each of the split data, split data information, and connection data information into a dividing/connecting information table. The work flow control engine renews the data start and end positions in the dividing/connecting information table in accordance with increase/decrease of the split data processed in each of the branch destination nodes.
