Distinguishing class structure from classifications

A classification is a word, although it can be a number or an alphanumeric, that describes something. For example, you could have a classification called ROLLER. The parent classification is BEARING. So the classification path, or the class structure, is BEARING \ ROLLER. This does not mean that ROLLER must always be used with bearing. This is just one instance of it.

If you had a classification of BAKING, you could create a classification path of BAKING \ ROLLER.

You could also have a classification of STAINLESS STEEL. If you had roller bearings made from stainless steel, you could have a classification path of BEARING \ ROLLER \ STAINLESS STEEL.
