PROBLEM TO BE SOLVED: To support flexible concurrent engineering by leading out other engineering information to be influenced by the change of one engineering information stored in a data base when the one engineering information is changed. SOLUTION: When one engineering information stored in the database 3 is changed based upon at least one information out of a tool information stored in an engineering tool information storing part 8, a database information stored in a database information storing part 5 and a user information stored in a user information storing part 7, other engineering information to be influenced by the changed engineering information is led out. Consequently flexible concurrent engineering considering the level of influence of a change in a certain data upon other work can be supported under a condition frequently generating a non-routine and return process.
