OFF should follow the same algorithm as the Disk Of Five Algorithm:
OFF should follow the same algorithm as the Disk Of Five Algorithm:
* ''assign OFF product category'' - each product should have a product category assigned, otherwise the DOF can not work;
* ''assign OFF product category'' - each product should have a product category assigned, otherwise the DOF can not work;
−
* ''map product category to DOF categories'' - t is attempted to map the OFF category to a DOF category:
+
* ''map product category to DOF categories'' - it is attempted to map the OFF category to a DOF category:
−
** each OFF category should correspond to a DOF category. As there are only a limited number of DOF categories, this can fail. The product is then unrecognised with respect to DOF.
+
** success - the OFF category correspond to an existing DOF category. We can continue the analysis:
+
*** assign DOF slice - determine in which slice the product belongs;
+
** ''no success'' - each OFF category should correspond to a DOF category. As there are only a limited number of DOF categories, this can fail. The product is then unrecognised with respect to DOF. It should get the label '''unrecognised DOF category'''.
