In a data processing apparatus, when an instruction for starting validation is provided, or when definition information is updated, data input from a data source is collected, and a process for narrowing down of the collected data is executed. In the data narrowing process, by extracting records and items as process targets according to the definition information that defines the operation of the apparatus, the number of data items used for validation is reduced. Then, the operation is validated using the narrowed data. In the operation validation process, a virtual transfer destination of output of data is provided within the apparatus, and the data is output to the virtual transfer destination, for comparison with the output data, whereby the validation of the operation is performed.
