A fuzzy database is a database that can process fuzzy data. The general database is based on two straight logic and accurate data tools, and cannot express many ambiguous things. With the establishment of fuzzy mathematics theory system, people can use quantity to describe fuzzy events and can perform fuzzy operations. In this way, the incomplete, uncertainty and fuzziness can be introduced into the database system so as to form a fuzzy database. The research of fuzzy da
