In this paper, the dependency of attributes in information systems has been used to define a finer quasi-discrete topology in information systems. This topology gives the characterization of roughness properties of sets. It is shown that every rough subset in the finer quasi-discrete topology is rough in the coarser quasi-discrete topology.
