Two classes of hierarchical relationships that are determined. It is useful in the hierarchical models construction, and in related concepts of generalized tree structures. It is studied the kinds of hierarchies, reducible to each other, as well as the possibility of a correct determination of level stratification systems. Hierarchical relations and related concepts are compared. The above concept should be used in the teaching of computer science and other disciplines that require a precise definition of the hierarchy.
