1. A method for the dynamic retrieval of assigned application data, comprising: providing master data including an input set G of hierarchically organized data g; a condition set M of hierarchically organized data constraints m; for each element g of the input set G a static condition assignment set IM(g) with elements m of the condition set M; for each element (g,m) of the Cartesian product of the input set G and the condition set M a static value assignment set IP(g,m) with data associations P included in a value set P; and dynamically determining from the master data for an element g of the input set G an application assignment set A(g) with elements (m,p) of the Cartesian product of the condition set M and the value set P, taking into account the hierarchical organization of the input set G and the condition set M.
