Abstract

The advent of low-cost high-resolution graphical workstations led to a new generation of interaction tools (often called Visual Languages) in information systems, where the use of graphics enhances the quality of the interaction. Unfortunately, in contrast to traditional (textual) query languages, no general framework exists where any visual language can be formally represented to evaluate its expressive power. Hypergraphs appear good candidates for being a very natural mathematical counterpart of arbitrarily complex visual structures. In this paper we present a particular kind of hypergraph, the Structure Modeling Hypergraph, as a representation tool able to capture the basic features of existing data models and well fit to define a set of basic graphical interaction primitives, in terms of which more complex interaction mechanisms may be described and compared.
