The importance of designing query systems which are effective and easy to use has been widely recognized in the database area.

Experimental results indicate that the effectiveness of a diagrammatic or an iconic query language varies depending on the classes of queries and the kinds of users. This supports the opinion that an interface offering to the user various visual representations and query modalities is the m...
