To solve the problem wherein when approval data is added or changed in electronic approval systems, many objects must be modified, such as an approval input screen, an approval processing screen and a database structure, and the electronic approval systems are difficult to configure flexibly and quickly.

A user of a client computer 1 enters and holds approval data into the electronic application form, and sends it to an approver of an approval computer 2 by the approval function programs attached in advance. When the approval data is modified, the electronic application form is modified on the electronic application form creation computer 3 and sent to the user of the client computer 1.
