The Proper Hardware Maintenance data are grouped into clusters at one or more levels, and the influence of the clusters on the data points contained in the datas from the hardware maintenance is taken account for the other statistical analysis. In this example, the top-most of the heirarchy table is the Computer Hardware Maintenance, therefore it is where the other topics branch out from to extend to other topics that are still covered by hardware maintenance.                This Relational Model (RM) represents the database of Proper Hardware Maintenance,this relation is a table of
