Abstract
In an expert system of an operating system e.g. an industrial plant it is desired to input data in the form of relationships between operating parameters of the system to a database. However, if such data are input by inexperienced users, there is the possibility of incorrect data being input. Therefore, a memory stores a plurality of fundamental rules, each being a predetermined relationship between the operating parameters. Then when a datum is input, the fundamental rule(s) corresponding to the operating parameters of the datum are investigated, and the datum is transmitted to the database when each such corresponding fundamental rule is satisfied. In a further development, prevent transmitting datum to a database when each such corresponding fundamental rule is not satisfied.
