PURPOSE:To eliminate a conversion leakage due to an operator's mistake when a source type is converted to an object type by developing other facility data referring to facility data when the facility data is subjected to a maintenance. CONSTITUTION:An operator instructs data group type to be converted through a man-machine 11 to a conversion instruction input unit 14. The unit 14 which receives the instruction instructs a conversion to a facility data converter 15. The converter 15 refers to a facility data relation list 16 to notify data group type by referring to the facility data of the instructed data group type. Then, the facility data of the data group type instructed and the facility data of the data group type referring to the facility data are produced from facility data source 13, converted, and the data base object obtained as a result is written in a facility data object 17. |
