We discuss various ideas how to implement execution of approximate SQL statements within Infobright database engine. We first outline the engine's architecture, which is designed entirely to work with standard SQL. We then discuss several possible extensions towards approximate querying and point out at some analogies with the principles of the theory of rough sets. Finally, we present the results of experiments obtained at the prototype level, both with respect to the speed of query execution and the accuracy of approximate answers.
