ABSTRACT
<p>The universal-relation model is introduced, and its fundamental ideas are outlined. This model keeps access-path independence by removing the need for logical navigation among relations. One benefit is a simple yet powerful query-language interface. Two universal-relation database-management systems are discussed that provide good examples of the model: System/U, developed at Stanford University, and FIDL, developed at International Computers Ltd. in Britain.</p>
