Train lines can be effectively created, shared by a plurality of users. Upper users can edit the train lines created by general users and make engagement person change. A diagram management server stores user information defining a relationship between a login user and an authority level; train line information; and authority setting information defining a relationship between a creation person having edit authority of the train line and an upper user in database. When the login user is defined as upper user of the creation person in the authority setting, the diagram edit terminal requests register and update of the train line information created by the creation person based on authority level of the login user, and the diagram management server resisters and updates the train line information. Then, from database, the diagram edit terminal acquires the train line information that the login user has the edit authority, and displays the train line information. |
