In the paper we present the definition of
Pawlak’s
model of an information system. The model covers information systems with history, systems with the decomposition of objects or attributes and dynamical information systems. Information systems are closely related to rough set theory and decision support systems. The aim of the paper is to characterize the stimulated by Professor
Pawlak
research of the group in Silesian University in information retrieval based on different information systems and in decision support based on rough sets, and to outline the current research projects of this group on modern decision systems.
