Abstract
The Universal Relation (UR) model has been researched with the ultimate objective to free the user from logical navigation in a relational database. There have been many different suggestions as to how to implement a UR interface. Nested relations have been recently suggested as a way of extending the applicability of the classical relational model. In this paper we establish a strong connection between the UR model and nested relations. Thus, nested relations are shown to be a suitable internal level for implementing efficiently a UR interface.
