The essay researches the issue of fuzzy set theory which is applied to database search optimization. In order to solve the problem that it is difficult to retrieve information and the efficiency of search is low, propose a method which makes fuzzy set theory to apply to the relational database. According to defining the equivalent relation and equivalent class for certain attributes domain of database, then the data of database is divided into different groups. On the basis, the membership function would be further grouped for database to decrease the number of groups and to make the data position more accurate.
