Abstract

This paper provides a method of implementing security mechanism in program in according to the features of a multi-user database application system. It is the method that set the password as a property of each table, and the properly must be compared with a password when operating table. The result is that every user can query data, but only the certain user who has the password can do the operation of insert, update and delete.
