Abstract (en)

[origin: WO2007137308A1] The invention relates to a method for controlling a relational database system, wherein a request statement comprising key words is initially analysed using a recursive transition network (RTN). Said RTN consists of RTN modules which are independent from one another and each RTN module has an internal, oriented decision graph which is defined independently from the internal, oriented decision graph of the other RTN modules, said RTN comprising at least one decision position along at least one decision path. In a selection step, the internal decision graphs of all of the RTN modules are transversed by key words, and all possible paths of said decision graphs are transversed until either no coincidence is determined with the respectively selected path in the decision graph and the process is interrupted or the respectively selected path is transversed until the end.
