DATA REGISTERING METHOD

PROBLEM TO BE SOLVED: To guarantee the consistency between graphic data and attribute data. SOLUTION: One operator starts a process for connecting to a data base and makes a connection with a graphic data base (S11). When a mesh to be registered is connected, it is judged whether or not it is locked (S12). When a lock-ON state is judged, the registration is quit, a process S22 is moved to, and the connection with the graphic data base is finished. If a lock-OFF state is judged in S12, the mesh is connected (S13). Then another operator makes a connection with an attribute data base (S14) and tries to make a connection with a table to be registered. At this time, it is judged whether or not a lock is made (S15). When the lock is made, the registration is quit, a process S20 is performed, and the connection with the attribute data base is finished. If the lock is OFF in S15, on the other hand, a connection with the table to be registered is made (S16). Then attribute data and graphic data are registered newly or by updating (S17) (S18).
