PURPOSE:To reduce a load on a user by deciding the necessity of conversion of a data format by comparing the data format of data to be processed with that of the data to be executed, and performing the conversion automatically by using a conversion rule when it is needed. CONSTITUTION:The data in a data storage means 2 is compared with the input data format of the next processing designated by a procedure execution means 5, and the data in the data storage means 2 is converted by a data conversion means 6 when it is necessary to convert the data format according to a data format conversion rule 8, and a data processing is executed by a data processing execution means 9. Therefore, it is not required to recognize the input data format requested by a processing to be executed, and also, in case of performing plural processings successively, it is not required to consider a difference between the output data format of the processing executed at a preceding stage and that of the processing executed at a succeeding stage. Furthermore, it is not required to consider the processing for the input data format in each processing. In such a way, it is possible to reduce the load on the user. |
