GDF-DATA BANKS has begun effectively its activity in 1993 after a long and intense experience in testing a wide variety of raw materials up to end products and designing original and highly efficient testing techniques.

As a result of designing efficient experiments and retrieval of experimental data, new theoretical and practical principles were established – topoenergetic theory, defining the behaviour of composite systems in any operating and/or processing conditions.

These new working principles impose some particular conditions in performing experiments in view to obtain basic experimental data able to be condensed in 3 ontogenic parameters univocally defining the behaviour of tested sample. These parameters define the nature and the amplitude of transforming process triggered by testing experiments having direct structural significances. For different samples tested in same conditions, it is possible to compare quantitatively the nature and amplitude of their behaviours, so phylogenic groups of samples with the same nature can result quantitatively defined by phylogenic parameters. These parameters establish true DATABANKS and ensure: (i) structural identification of an unknown sample; and/or (ii) the optimization of an imposed behaviour for tested samples by exact structural modifications.
