The importance of designing query systems which are effective and easy to use has been widelyrecognized in the database area. Also, it is well known that the adequacy of a system should be testedagainst actual users in a well monitored experiment. However, very few such experiments have beenconducted. The objective of our study is to measure and understand the comparative ease with whichsubjects can construct queries in two kinds of visual languages, one diagrammatic and the other iconic.More specifically, we are interested in determining if there is significant interaction between: 1) the queryclass and the query language type; and 2) the type of query language and the experience of the user.Experimental results indicate that the effectiveness of a diagrammatic or an iconic query language variesdepending on the classes of queries and the kinds of users. This supports the opinion that an interfaceoffering to the user various visual representations and query modalities is the most appropriate for a wide setof users and applications.Keywords: Human-Computer Interaction; Query Languages; Visual Interfaces; Usability; Experiment.
