Abstract
This article defines information systems as reflexive transitive binary relation family. It is equivalent to the attributes of information systems expressed as functions. This article has studied the composion operations of the information system attributes, attribute reduction representation and the minimum element method of attribute reduction. Finally, the results of the example show that the new algorithm has good efficiency.
