Abstract: Without using a host computer, a computer program for object business processing is efficiently developed in a work station. A data flowchart generation unit, a system flowchart generation unit, and a program specification generation unit are provided in a distributed processor such as a work station. First of all, edit of a data flowchart of business processing which becomes the object of software development is performed. Data items extracted at this time are entered into a data item dictionary so that they may be handed over and used as input information of a data analysis unit. As for functions extracted in the edit process of the data flowchart, they are successively generated as a system flowchart and program specifications. Finally, a source program is generated.
