Abstract: There are provided a batch processing apparatus and a batch processing method capable of significantly reducing the burden on a system designer, a system administrator, and an operator operating the system as well as significantly reducing the development cost. The batch processing apparatus acquires from a repository the metadata defined as information on at least data item name, input, processing content, and output, as well as information stored and registered in advance in the predetermined repository, inputs input data according to a declaration process of the acquired metadata, creates output data by processing the input data, and outputs the output data. Herein, the batch processing apparatus creates the output data by changing all the output data related to the metadata according to change of the metadata.
