| Abstract: | Information system is a databases have relations between object and property.It is the basis of all kinds of reduction to uncover the essence property of attributes and portray the importance of it.This paper improved the importance measure of attributes based on the equivalence relation,and the equivalent charactertions of it based on the partition was provided,which will simplify the operation steps and improve the computing efficiency. |
