A system and method is provided which represents hierarchical relationships. These relationships are statically stored in a compact manner that allows for easy determination of relations (such as dominance) between any two entities defined to the hierarchy. This stored information is referred to a dominance key or a DOMKEY. DOMKEYs, rather than storing the actual relationship between entities defined to the hierarchical structure, store a representation of the structure itself. In a preferred embodiment, the present invention is applied to computer security systems such as the RACF system and is embedded in a RACF administrator such as Vanguard Integrity Professionals VRA RACF Administrator.
