<P>PROBLEM TO BE SOLVED: To prevent that the same information is present in a plurality of lines or that addition of information is processed as a change, by synchronous processing of a plurality of tables. Ž<P>SOLUTION: It is assumed that columns of labels and columns of values are present in the plurality of tables. About a line transmitted from an information source, the following processing is performed. When the labels are equal and when the values vary, it is assumed as update of the value, and a value imparted from the information source is overwritten into the label in a corresponding line of a synchronous target table. When the values are equal and when the labels vary, it is assumed as a change of the label, and the transmitted label is overwritten into the corresponding line of the synchronous target table. When both the labels and the values are equal, it is assumed that the change is absent, and nothing is performed to the corresponding line of the synchronous target table. When the labels and the values are not equal about all the lines of the synchronous target table, it is assumed as addition of a new line, the new line is added to the synchronous target table, and thereafter, the transmitted label and value are copied.
