Abstract:Because soft set and information system are both dealing with objects and attributes or parameters, they must have the intimate connections. However, this connection is still not completely understood. we will study the relations between soft set and information system. In this paper, The category SS(U) of soft sets over U is discussed, then we prove that the category SS(U) is a topos.
