A method for controlling a relational database system, with a query statement comprised of keywords being analyzed with the RTN being formed of independent RTN building blocks with each RTN building block having an inner, directed decision graph which is defined independently from the inner, directed decision graphs of the other RTN building blocks with at least one decision position along at least one decision path. with the inner decision graphs of all RTN building blocks by means of the keywords being run in a selection step and all possible paths of this decision graph being followed until either no match with the respectively selected path is determined by the decision graph and the process is interrupted or the respectively chosen path is run until the end.
