Abstract: The present invention relates to a database system for ideograms and a processing method thereof. The database system includes an ideogram database having fields in which shapes of characters constituting the ideograms are separated into Chinese radicals comprised of dots and strokes, each Chinese radical comprising one stroke count, a sequence is assigned to each of the Chinese radicals, and the respective ideograms are arranged according to the sequences of the Chinese radicals and a stroke order of each ideogram; and a list window for searching the ideogram database for the ideograms based on the arranged sequences of the ideograms.
