Abstract: The present drawing data stored in the present drawing data storage unit is compared with the preceding drawing data stored in the preceding drawing data storage unit for each of the drawing areas divided by the area dividing unit, thereby determining whether there is a change in the preceding drawing data for each of the drawing areas in the present drawing data. Then, control is performed to transmit to the client apparatus the drawing data in a drawing area determined to have a change by the comparison decision unit, except for a drawing area of the present drawing data determined to have no change by the comparison decision unit. Consequently, it is possible to remarkably reduce the amount of data transferred to the client apparatus as a result of a change in the drawing and therefore transfer the drawing data at high speed.

Abstract: An ordinary person in charge is enabled to easily construct or modify a business processing system only by making a business flow diagram indicating the flow of the business to be adaptable to the contents of the business of the department to which the person in charge belongs if the person in charge understands the business system and slips and vouchers which are daily used without a necessity of requesting a system engineer having exclusive knowledge about programming to design the business processing system. Thus, a required business process can be performed. When the business flow diagram indicating the flow of each business in the own department has been made, a business constructing system analyzes the business flow diagram to make a slip registration card, an original register registration card and a voucher registration card.
