the one that is higher in the hierarchy or the tier levels would be used in priority to the other in the event of two providers in the same tier responding which ever one responded first would be used returning to fig1 in its preferred embodiment the invention is practiced by first being begun 101 which step includes loading the invention into computer memory so that automatic interaction with requesting applications can occur next the process of the invention is initialized by opening processing and closing the configuration file 102 of the computer system the u201c tier u201d variable is set to initialized 103 by being set to one the each module listed in the tier u201c tier u201d in the first instance tier 1 is loaded and executed 104 in the preferred embodiment of the invention this code is located in treefactory loadtiero routine next the tier number u201c tier u201d is incremented in the first instance to tier 2 105 the tier number is checked to see if it exceeds the total number of tiers available 106 if it does not exceed the number of tiers available then the process returns to step 104 of loading and executing each module listed in the tier u201c tier u201d if the value of u201c tier u201d exceeds the total number of tiers available then the process ends fig2 shows further detail as to the preferred embodiment of the u201c load and execute module u201d step of the invention as shown in fig1 step 104 first the module is initialized.
