Abstract Algebraic system of decision logic and topological algebraic system of universe are set up based on information system. Then relation theorem of the two systems is discovered. With the two algebraic systems, granular world models are established, in which the mechanism of granular computing (GrC) is studied by analyzing concept learning and rule acquiring. In the meantime, the model provides coherent explanation of all granular computing methods, which leads to unification of set based granular calculation and decision logic based granular calculation to some degree.
